In two-cylinder engines, the cylinders can either fire simultaneously (such as in a flat-twin engine) or one after the other (such as in a straight-twin engine).For V engines and flat engines, the numbering system is L1 for the front cylinder of the left bank, R1 for the front cylinder of the right bank, etc. For example, a V6 engine could have cylinders A1-A2-A3-B1-B2-B3, with cylinders A1 and B1 located at the power output end of the engine.įiring order shown on a Lycoming R-680-13 9-cylinder radial engineĬommon firing orders are listed below. Large diesel truck and locomotive engines, particularly of European manufacture, may also be numbered this way.Ĭylinders on V engines often include a letter representing the cylinder bank. Numbering systems for ship engines Ĭontrary to most car engines, a ship's engines are often numbered starting from the end of the engine with the power output. This is the case for the Citroën Traction Avant and many rear-engine cars. the transmission is closer to the front of the car than the engine), cylinder #1 is located towards the rear of the car. As a consequence, the left bank of a transversely V engine is usually closest to the front of the car.įor cars where the engine is installed 'backwards' (i.e. Most transverse engine front-wheel drive models have the front of the engine at the right-hand side of the car (except for many Honda cars). The left bank of the engine is on the left side of the car (when looking from behind the car), and vice versa for the right bank of the engine.įor a transverse engine located at the front of the car, whether the front of the engine is at the left-hand or right-hand side of the car is best determined based on the side of the car where the transmission is located (which corresponds to the rear of the engine). This illustrates that the rear of the engine is the end that connects to the transmission, while the front end often has the drive belt for accessories (such as the alternator and water pump). The simplest situation is a longitudinal engine located at the front of the car, which means the engine's orientation is the same as the car's. The cylinders are numbered around the circle, in clockwise direction with the #1 cylinder at the top. This was done so that all Ford engines would have cylinder #1 on the right bank and all Pontiac engines would have cylinder #1 on the left bank, to simplify the process of identifying the cylinders. However, the Ford Flathead V8 and Pontiac V8 engine actually have the #1 cylinder behind the cylinder from the opposite bank. The selection of whether the #1 cylinder is on the left bank or right bank usually depends on which bank is closer to the front of the crankshaft. This approach is typically used by V8 engines from General Motors, and Chrysler. 1-3-5-7 along the right bank and 2-4-6-8 along the left bank). Numbering the cylinders based on their position along the crankshaft (e.g.This approach is typically used by V8 engines from Audi, Ford and Porsche. 1-2-3-4 along the left bank and 5-6-7-8 along the right bank). Numbering the cylinders in each bank sequentially (e.g.The frontmost cylinder is usually #1, however there are two common approaches: V8 engine with cylinder numbering based on crankshaft position (instead of following each cylinder bank)
