Timing belt (camshaft) In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the ...
Ignition timing. Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of ...
Nissan QR25DE Engine. The QR25DE is a 2.5 L (2,488 cc) variant built with cast steel connecting rods, a steel timing chain, counter-rotating balance shafts, and an aluminum intake manifold. The engine bore and stroke is 89 mm × 100 mm (3.50 in × 3.94 in) and a compression ratio ranging from 9.5:1 to 10.5:1 depending on the vehicle.
Camshaft. In four-stroke cycle engines and some two-stroke cycle engines, the valve timing is controlled by the camshaft. It can be varied by modifying the camshaft, or it can be varied during engine operation by variable valve timing. It is also affected by the adjustment of the valve mechanism, and particularly by the tappet clearance.
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open. Interference engines rely on timing gears ...
The Smartstream G1.5 T-GDI (G4LH) is a turbocharged 1,482 cc (1.5 L) inline 4-cylinder engine with GDi from the Kappa family that carries a bore and stroke of 71.6 mm and 92 mm [ 12] respectively and a 10.5:1 compression ratio; it makes 160 PS (118 kW; 158 hp) at 5,500 rpm and 25.8 kg⋅m (253 N⋅m; 187 lbf⋅ft) of torque between 1,500 and ...
The first implementation of the Atkinson cycle was in 1882; unlike later versions, it was arranged as an opposed-piston engine, the Atkinson differential engine. [6] [7] In this, a single crankshaft was connected to two opposed pistons through a toggle-jointed linkage that had a nonlinearity; for half a revolution, one piston remained almost stationary while the other approached it and ...
Ford EcoBoost engine. I3 1.5: Bosch MG1CS016 with CAN-Bus and individual cylinder knock control. FGEC software. EcoBoost is a series of turbocharged, direct-injection gasoline engines produced by Ford and originally co-developed by FEV Inc. (now FEV North America Inc.). [ 6] EcoBoost engines are designed to deliver power and torque consistent ...
