The GM High Feature engine (also known as the HFV6, and including the 3600 LY7 and derivative LP1) is a family of modern DOHC V6 engines produced by General Motors. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ). It is a 60° 24-valve design with aluminum block and heads and sequential multi-port fuel ...
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
Unlike a turbine engine, a hot start is unlikely to damage a reciprocating fuel injected engine. However, with improper starting procedure the situation may progress to the point that the operator depletes the starter battery before successfully starting the engine and there is risk of battery or starter damage and excess wear due to these ...
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines.These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line.
In a six-cylinder engine with an even firing interval, the next piston starts its power stroke 60° before the previous one finishes, which results in smoother delivery of power to the flywheel. Comparing engines on a dynamometer, a V6 engine shows instantaneous torque peaks of 154% above mean torque and valleys of 139% below mean torque, with ...
Lean-burn gas engines are almost always turbocharged, resulting in high power and torque figures not achievable with stoichiometric engines due to high combustion temperatures. Heavy duty gas engines may employ precombustion chambers in the cylinder head. A lean gas and air mixture is first highly compressed in the main chamber by the piston.
The latter was offered in various models through 1988. From 1986, the 3.8 had a revised, crankshaft-driven oil pump which eliminated a longstanding problem with pump housing wear and loss of prime. Power produced by this engine was: VIN code B (LG2): flat lifters (tappets) 140 hp (104 kW) at 4,400 rpm, 200 lb⋅ft (271 N⋅m) at 2,000 rpm
The Group 1 engines were the smallest in displacement and outer dimensions, and differed most significantly from the larger Group 2 and Group 3 engines by having only four main bearings (whereas the Group 2 and 3 engines had seven) [1]: 15 and a different firing order (1-5-3-6-2-4, whereas the others are 1-4-2-6-3-5).
