GM 2.7L I-4 TURBO L3B ENGINE
The GM L3B is a turbocharged gasoline engine produced by General Motors for use in various vehicles, including full-size pickup trucks and cars. Displacing 2.7 liters in an inline-four cylinder configuration, the L3B is a clean-sheet design for General Motors. The engine was developed from the outset as a truck engine.
- GM's first use of Active Fuel Management (cylinder deactivation) on a four-cylinder engine.
- High- and low-lift valve profiles.
- Continuously variable valve timing.
- High valve lift for full power.
- Low valve lift for balance for power and efficiency.
- Active Fuel Management shuts down two of the cylinders in light load conditions to further conserve fuel.
- Dual-volute turbocharger housing for improved throttle response and low-speed torque.
- A variable-pressure oiling system with a continuously variable-displacement vane oil pump enhances efficiency by optimizing oil pressure as a function of engine speed and load. With it, the oil supply is matched to the engine requirements rather than the excessive supply of a conventional, fixed-displacement oil pump.
- GM's first application of Active Thermal Management, which helps the engine warm up faster and achieve its optimal engine temperature for performance and efficiency. The system uses a rotary valve system to distribute coolant through the engine in a targeted manner. It sends heat where it's needed to warm up the engine to reduce friction and heat the cab, or cools when needed for high power operation. The result is improved engine performance in hot and cold ambient temperatures.
- An electric water pump - a first for GM trucks - support Active Thermal Management system and further enhances the engine's performance and efficiency by eliminating the parasitic drag that comes with a conventional, engine-driven water pump. It also enables continues cabin heating even when the engine is disabled by the stop/start feature.
- Direct fuel injection is used to optimize efficiency and performance. With direct injection, a higher compression ratio (10.0:1) is possible because of a cooling effect as the injected fuel vaporizes in the combustion chamber, reducing the charge temperature and improving resistance to spark knock. Direct injection also enables gas scavenging from the combustion chamber to the turbo for fast response.
- Dual overhead camshafts contribute to the 2.7L Turbo's smoothness and high output, with dual independent continuously variable valve timing working with the valvetrain to deliver optimal performance and efficiency. The dual independent system, which allows the intake and exhaust valves to be phased as different rates, promotes linear delivery of torque with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement) without sacrificing overall engine response or drivability.
- An integrated exhaust manifold that is part of the cylinder head assembly and recovers exhaust heat for faster engine and transmission warmup, with quicker turbo response.
- Oil jets located in the block are employed for performance and temperature control. They target the underside of the pistons and the surrounding cylinder walls with an extra layer of cooling, friction-reducing oil. The jets reduce piston temperature, allowing the engine to produce more powerful and enhance long-term durability.
- Stop/start technology that automatically stops the engine in stop-and-go traffic for fuel efficiency, enhancing fuel economy in city driving. The driver-selectable system shuts off the engine at stoplights and certain other stop-and-go situations, saving fuel. The engine automatically restarts when the driver takes their foot off the brake.
