It is part of the large-displacement four-cylinder Ecotec engine family. The turbocharger is capable of generating up to 20 ecotec 2.0 turbo cutaway engine video of boost and its twin-scroll design ecotec 2.0 turbo cutaway engine video deliver the usable power from the engine — effectively eliminating the universally-hated turbo lag while supplying a broad power band.
This gives allows the LTG to respond rapidly to throttle input — a quality often associated with a higher-displacement naturally aspirated high-performance engine. Performance and efficiency are further optimized by electronically controlled supporting components including the wastegate and bypass. The LTG is not related to the outgoing 2. Engine highlights include: Engine Block: It is dimensionally similar to previous Ecotec turbo ecotec 2.0 turbo cutaway engine video variants, while providing improved structural support, as well as enabling greater control of noise, vibration ecotec 2.0 turbo cutaway engine video harshness.
The main bearing bulkheads, which support the crank bearings, as well as the cylinder bore walls have been significantly strengthened to support increased engine loads. Rotating Assembly: Forged powdered metal connecting rods incorporate a larger, forged I-beam cross section for added strength in this turbocharged application. The pistons in the 2. This enhances efficiency and the feeling of performance as the rpm increases.
The tops of the pistons have a dish shape that deflects injected fuel. Each piston has its own directed jet that sprays oil toward its skirt, coating its underside and the cylinder wall with an additional layer of lubricant. The head is also designed specifically for direct injection. In other Ecotec engines, the fuel injectors are mounted in the intake ports but the LTG 2. Apart from injector installation, the head has conventional port and combustion chamber designs, with both being optimized for direct injection and high boost pressure.
The head uses stainless ecotec 2.0 turbo cutaway engine video intake valves that are nitrided for improved durability and undercut to improve flow and reduce weight. The exhaust valves have sodium-filled stems that promote valve cooling. At normal engine operating temperatures, the sodium inside the valve stem fuses and becomes liquid.
The liquid sodium improves conductivity, promoting heat transfer away from the valve face and valve guide to the cooler end of the stem, where it more readily dissipates. This helps maintain a lower, more uniform valve temperature, reducing wear on the valve guide for better alignment and a consistent seal between the valve seat and valve face over the life of the engine.
Performance was the priority with the LTG Ecotec 2. It is extremely durable and delivers exceptional airflow qualities. This arrangement is integrated on the LTG Ecotec 2.
Both the intake and exhaust cams have hydraulically operated vane-type phasers that are managed by a solenoid mario gotze goal vs argentina dailymotion er directed by the engine control module ECM.
The phasers turn the camshaft relative to the drive sprocket, allowing intake and exhaust valve timing to be adjusted independently. Cam phasing changes the timing ecotec 2.0 turbo cutaway engine video valve operation as conditions such as rpm and engine load vary. It allows an outstanding balance of smooth torque delivery over a broad rpm range, high specific output and good specific fuel consumption. Direct Injection: It fosters a more complete burn of the fuel in the air-fuel mixture, and operates at a lower temperature than conventional port injection.
This allows the mixture to be leaner less fuel and more airso less fuel is required to produce the equivalent horsepower of a conventional, port-injection fuel system. Direct injection also delivers reduced emissions, particularly cold-start emissions, by about 25 percent. The higher compression ratio with direct injection is possible because of a cooling effect as the injected fuel vaporizes in the combustion chamber, which reduces the charge temperature to lessen the likelihood of spark knock.
The direct injection fuel injectors have been developed to withstand the greater heat and pressure inside the combustion chamber, and feature multiple outlets for best injection control. The fuel system operates at pressure as high as 2, psi, compared to about 60 psi in conventional port-injected engines.
The engine-mounted fuel pump is augmented by a conventional electrically operated supply pump in the fuel tank. The fuel delivery system features a high-pressure stainless steel feed line and a pressure-regulated fuel rail without a conventional fuel return line from the engine to the tank.
Fuel pressure varies from about psi at idle to 2, psi at wide-open throttle. Rather than the linear operation of a conventional fixed-flow pump, the variable-flow ecotec 2.0 turbo cutaway engine video features a crankshaft-driven oil pump that matches the oil supply to the engine load. This prevents using energy to pump oil that is not required for proper engine operation. An engine oil cooler helps maintain optimum oil temperatures. It has a heat exchanger incorporated into the oil filter housing.
The design optimizes oil cooling with a minimal pressure loss. During cold starts, the system also enables faster heating of the engine oil for an earlier reduction of internal engine friction. Twin-Scroll Turbocharger: Each of two scrolls on the turbine is fed by jef r holland sanctify yourselves video er separate exhaust passage — one from cylinders one and four, the other from cylinders two and three — virtually eliminating turbo lag at low engine speeds, giving the engine immediate throttle response associated with a naturally aspirated high-performance engine.
The turbocharger generates maximum boost of about 20 psi. Because direct injection cools the intake process compared to port injection, it allows the LTG Ecotec 2. Air-to-Air Intercooler: The LTG Ecotec 2. Inlet temperature is reduced as much as degrees F degrees C. Cooler air is denser, which means more oxygen is packed into the cylinders for optimal combustion and, consequently, greater power. Cam-Driven Vacuum Pump: The pump is mounted at the rear of the cylinder head and is driven by the exhaust camshaft via a flexible coupling.

There are many topics covered in this book to show you how to get the most from the Ecotec LSJ-powered vehicle.
This first chapter is loaded with information on the Ecotec engine family, some early motorsports usages of the LSJ engine and what to look for in the future. This vehicle was developed by the GM Performance Division for all around performance.
Whether you are a four-cylinder engine performance enthusiast or not, chances are the performance, elegantly simple design and available power upgrades these engines respond to will impress as you learn more about the overall Ecotec engine family and especially the LSJ engine. It is the sleeper performance car of the entire GM fleet—this thing flies! They looked across the entire GM global enterprise to determine what vehicles were planned for the future, what consumer desires were, and how they could meet those desires with one four-cylinder engine architecture.
In the U. The European customer leans toward manual transmission vehicles and is more than happy to run an engine in the upper end of the powerband to take advantage of high rpm horsepower.
Then, there are locales like Canada and other parts of the world that are predominantly powered by four-cylinder vehicles that need a diverse lineup of engines to satisfy the many needs within a marketplace. Now you get an idea how complex it is to build one ecotec 2.0 turbo cutaway engine video gasoline engine architecture ecotec 2.0 turbo cutaway engine video meet the needs of the global economy. Design Decisions With all that said, the team narrowed in on a few constants.
The block, cylinder head and accessory bracketry would be. The engine architecture would utilize chain-driven dual overhead camshafts for durability, a four-valve-per-cylinder valvetrain for volumetric efficiency and cast iron cylinder bore liners would be pressed into the aluminum block to provide a rigid bore that could withstand higher cylinder pressures without flexing. This proposed four-cylinder engine design would be able to power both front- rear- and all-wheel drive vehicle designs, be configurable for variable valve timing, be able to handle forced induction and run on either traditional sequential intake runner-based fuel injection or direct fuel injection where the fuel injector sprays gasoline inside the combustion chamber.
After considerable discussion, Lotus Engineering UK was engaged as the base of the engineering operations. GM leadership and engineers from GM North America and GM Europe were brought together to work as a team in developing the hardware and software for what would become the Ecotec. They spent four years developing the basic design, testing prototype components and systems and preparing for the engine to be the global GM four cylinder architecture.
Were there tough compromises? You bet, but in general, the leadership. GM has built millions of Ecotec fourcylinder engines so far to power vehicles in every corner of the world.
Look for more variations off this excellent four-cylinder architecture ecotec 2.0 turbo cutaway engine video the future, as the Ecotec family continues to expand london times newspaper font produce ever more horsepower! For a breakdown of the many Ecotec RPOs, see the sidebar below. The only supercharged Ecotec engine, and easily upgraded in power with GM Performance Stage 1, 2 and 3 upgrade kits.
At the time, the Ecotec family consisted of some potent, naturally aspirated engines and a turbocharged engine was in the works, but nothing approached the torque and sword games for android. Ecotec 2. To resolve the issue, the leader of the GM Performance — Powertrain department, Jim Minneker, decided to build a hp version of the Ecotec with a small team of GM engineers. Minneker had been part of the team extremely aggressive, but we were testing that built SEMA show cars in years past the limits of our capability.
That car was fun to team continued to develop some options drive, the engine proved durable and the for increased power—and from that the show car development had given him an Stage 1, Ecotec 2.0 turbo cutaway engine video 2 and Stage 3 performance idea of how to do a supercharged four- upgrade kits were developed. The team cylinder Ecotec. The team started with the 2.
The forged crankshaft and connecting rods loaded in this engine make it a stout package that can handle the stresses creatEcotec LSJ Cylinder Head Combustion Chamber ed by the supercharger. The supercharger legal! The team was their time and money. They really exceedable to package the ed anything we could have imagined. Lost foam and sand cast aluminum with pressed-in cast iron cylinder liners, four bolts per cylinder, setup up for twin balance shaft vibration cancelling system.
The LSJ uses a 1. Cast aluminum with dual overhead camshafts, design capable of supporting active camshaft phasing for variable valve timing, direct fuel injection and more….
The 2. The LSJ crankshaft is a forged steel design that incorporates induction heat-treated fillets for added strength, and cross-drilled, chamfered oil passages ecotec 2.0 turbo cutaway engine video excellent lubrication characteristics. All the Ecotec engines come with eutectic cast aluminum pistons. The common pistons in the Supercharged and Turbocharged Ecotec engines have a 5. The Ecotec cylinder head has 16 valves at Valve actuation is accomplished via lightweight, direct-acting cam followers what looks like an upside-down rocker from a pushrod engine pivoting on stationary hydraulic lifters.
The lobes of the two camshafts press on these cam followers, which in turn open and close the valves. The system is compact, durable and elegantly simple—and it works! And to really put this in perspective, if you had a 7. The GXP Solstice is more than a big. The exhaust is a true dual outlet system and the body has increased openings in the front to allow air into the air-to-air intercooler and cooling system.
While this car has gotten rave reviews from the media and consumers for its street manners, it has shown itself to be a very capable ecotec 2.0 turbo cutaway engine video car. While the base hp Ecotec 2. With this in mind, the GM Performance Division did considerable engineering to develop a road race package that can be.
The RPO for this package is Z0K and it deletes certain heavy items like the air conditioning while adding a performance-intended suspension that is good enough it ended up being the suspension under the higher horsepower GXP Solstice.
Racers then need to install a rollcage, safety harness, fire suppression system, higher temperature brake pads, grippy tires and a GM Performance Division-engineered hardtop. The engine remains stock, as does the suspension. These races routinely start over 50 cars from every manufacturer you can imagine. Even better, Grand Am Cup rules are simple enough that much of the development used to go fast on the track can be translated into performance upgrades for the street.
See Chapter 4 for more. Starting with a production Cobalt SS Supercharged, the GM Performance engineering team had the car completely gutted, a racing rollcage added along with the other required safety equipment when driving in competition race seat, 5-point seat belts and fire suppression system. The part most interesting was that the GM Performance Stage 2 see Chapter 4 for the install on the Stage 2 and GM Performance Stage 3 just now becoming available to the public performance upgrade kits were refined on the Time Attack car.
Also, some wild innovations were tested on the car to determine if they would provide performance increases. One of these packages was a large tank filled with cold water to cool the inlet charge—it would heat up ecotec 2.0 turbo cutaway engine video immediately and provide no substantial power increase in a short amount of track time. The other was a computer-controlled 50 hp shot of nitrous used sparingly but to excellent effect.
Much of this nitrous control and calibration work made its way into the GM Performance Stage 3 performance upgrade kit that is just now becoming available. The Time Attack Cobalt engine was a testbed for the Stage 1, 2 and 3 performance upgrade systems. The Time Attack Cobalt Engine was handbuilt and for appearance, the block, girdle and heads were powdercoated black. The Time Attack Cobalt Engine is more stock than many would like to believe—yet made almost hp on a hp shot of plan b ballad of belmarsh album s The Time Attack Cobalt floorpan is as it came from the factory.
Notice the Ecotec 2.0 turbo cutaway engine video shock absorber reservoirs— these shocks are awesome in their adjustability. The trunk of the Time Attack Cobalt is filled with a quick-fill fuel tank, nitrous tank and battery. To handle the immense power and road loads, a Pontiac Grand Am knuckle arrow was modified to accept the lower A-arm ball joint and installed on the Time Attack Cobalt. The rear axle was modified by cutting off the ends and welding on Pontiac Grand Am fivelug hubs, installing a custom adjustable swaybar and relocating the Ohlins shocks and Hyperco springs.
Running an Ecotec 2. The carbon fiber and stock sheetmetal body is shown just prior to being painted up with Red Bull livery for competition. A stock-bodied Solstice was upgraded with a full rollcage, a fuel cell, modified steering system, permanently installed air-jacks for the rear and more. As with all GM Racing-developed engines, this engine package was refined on the dyno to have a wide powerband with maximum durability.
The car has run over mph with a modified Stage 3 performance upgrade on the engine. The engine has been breathed on with aftermarket forged aluminum pistons, more aggressive camshafts and valvesprings and a modified Stage 3 upgrade kit. Some of the pieces on this vehicle, like the multi-pass intercooler, helped to create the Stage 3 upgrade kit See Chapter 6 for more on the Stage 3 kit just now becoming available to the public.
The engine is controlled ecotec 2.0 turbo cutaway engine video the stock powertrain control module PCMbut with a modified calibration to take advantage of the low restriction intake and exhaust and internal upgrades— and helped with the Stage 3 upgrade calibration development.
