Output for all engines increased due to new "open flow" mufflers. The dual-snorkel air intake introduced on L82 cars the previous year was now fitted to all cars and the base engine now generated 195 hp (145 kW). The optional L82 engine increased to 225 hp (168 kW). This was the final year a manual gearbox could be ordered with the L82 engine.
The 2020 Corvette C8 was the first Corvette to have a rear mid-engine configuration, [108] GM's first since the 1984 Pontiac Fiero. The base Stingray coupe was introduced on July 18, 2019, with three launch colors, red (with the Z51 Package), white, and blue, and the convertible on October 2 at the Kennedy Space Center , joined by the C8.R race ...
The result was what GM dubbed the LT5, an aluminum-block V8 with the same bore centers as the L98, but with four overhead camshafts and 32 valves. Lotus also designed a unique air management system for the engine to provide a wider power band by shutting off 8 of the 16 intake runners and fuel injectors when the engine was at part-throttle ...
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu.The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.
A valvetrain is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine. [1] The intake valves control the flow of air/fuel mixture (or air alone for direct-injected engines) into the combustion chamber, while the exhaust valves control the flow of spent exhaust gases out of the ...
Variable valve lift (VVL) is an automotive piston engine technology which varies the height a valve opens in order to improve performance, fuel economy or emissions. There are two main types of VVL: discrete, which employs fixed valve lift amounts, and continuous, which is able to vary the amount of lift.
Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...
For an automobile engine the components through which the air flows to the engine cylinders, are collectively known as an intake system [4] and may include the inlet port and valve. [5] An intake for a hydroelectric power plant is the capture area in a reservoir which feeds a pressure pipe, or penstock , or into an open canal.
