Flat-four engines typically use a firing order of R1-R2-L1-L2. Straight-five engines typically use a firing order of 1-2-4-5-3, in order to minimise the primary vibration from the rocking couple. Straight-six engines typically use a firing order of 1-5-3-6-2-4, which results in perfect primary and secondary balance. However, a firing order of 1 ...
The 3.4-litre 90-degree V8 racing engine was designed from scratch; and drove the rear wheels through a six-speed electro-pneumatic sequential gearbox. Since its introduction in 2005 the engine, which initially produced 478 horsepower (356 kW) has been developed and modified to meet the changing regulations of both the ALMS and the ACO .
When introduced in May 2003, this 3.9 litre V8 was the highest power and highest torque diesel V8 fitted in any production car worldwide. This was the second 'new' V engine from Audi which utilises new technologies - including chain-driven overhead camshafts and ancillary units, following the 4.2 40-valve V8 petrol engine first seen in the B6 S4.

Most four-stroke straight-five engines use a firing order of 1-2-4-5-3. [citation needed] This firing order results in the minimal primary (crank speed) rocking couple, and is used by the Volvo Modular engine, VW/Audi straight-five engine, General Motors Atlas engine and Honda G engine. Straight-five engines typically have a 72 degree ...
Delage straight-eight racing engine Straight-eight engine with firing order 1-4-7-3-8-5-2-6. The straight-eight engine or inline-eight engine (often abbreviated as I8) is an eight-cylinder internal combustion engine with all eight cylinders mounted in a straight line along the crankcase.
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. [8] Out-of-balance inertia forces in the wheel can cause different vertical oscillations depending on the track stiffness.
A boxer-style flat-six engine is able to have perfect primary and secondary balance.As in other six-cylinder engines, the overlapping of the power strokes of the different cylinders (with a firing interval of 120 degrees in a four-stroke engine) reduces the pulsating of the power delivery relative to that of similar engines with fewer cylinders.
