Engine knocking. In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside ...
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder.
Cylinder head. In a piston engine, the cylinder head (aka " head ") sits above the cylinders, [1] forming the roof of the combustion chamber. In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins. In more modern overhead valve and overhead camshaft engines, the head is a more ...
The LLR also corrected the head issue found in the L52. It produces 242 hp (180 kW) at 5,600 rpm and 242 lb⋅ft (328 N⋅m) at 4,600 rpm. The engine redline is 6,300 rpm. [6] This five-cylinder engine achieves better fuel economy than the six-cylinder with more power and torque than the four-cylinder. [1] Applications:

Excessive hammer blow from high slipping speeds was a cause of kinked rails with new North American 4–6–4s and 4–8–4s that followed the 1934 A.A.R. recommendation to balance 40% of the reciprocating weight. Out-of-balance inertia forces in the wheel can cause different vertical oscillations depending on the track stiffness.
Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder heads, as manufactured, are usually suboptimal for racing applications due to being designed for maximum durability. Ports can be modified for maximum power, minimum fuel consumption, or a ...
Straight-three engine. A straight-three engine (also called an inline-triple or inline-three) [1] [2] [3] is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engines, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural ...
