Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle, extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
A four-stroke power valve is a device fitted to four-stroke engines that constantly adjusts the internal diameter of the exhaust system to better suit the speed of the engine. Yamaha was the first to develop such a system, called the Exhaust Ultimate Power Valve (EXUP). [1] It first appeared on the Yamaha FZR EXUP and was later used on many ...
It has the same horsepower rating as the H22A engine but a lower redline of 7200rpms because it has a longer stroke than the H22A. The H23A DOHC VTEC has 87 mm × 95 mm (3.43 in × 3.74 in) (bore and stroke) and the H22A DOHC VTEC has 87 mm × 90.7 mm (3.43 in × 3.57 in) (bore and stroke).
