Engine displacement is calculated based on bore, stroke length and the number of cylinders: [1] displacement = π ( 1 / 2 × bore ) 2 × stroke × n cylinders. The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds or torque at lower engine ...
This OHV (overhead valve) engine was produced through 1953. With a cylinder bore of 3.5625 inches (90.49 mm), this is the smallest low-deck engine. All four low-deck engines have a stroke of 3.8125 inches (96.84 mm) and used 7 inch long connecting rods.
Bore x Stroke 62.0×41.3 mm; Compression Ratio 11.5 : 1; Induction type Programmed Fuel-Injection (PGM-Fi) Power 38.7 PS @ 12.500 rpm; Features : Throttle by Wire, Riding Mode., Starter Electric Only; Honda CX500. Engine Type 498cc liquid-cooled two-cylinder "Flying V-Twin" four-stroke; Bore and Stroke 78.0 mm x 52.0 mm; Compression Ratio 10.0:1
An engine is described as oversquare or short-stroke if its cylinders have a greater bore diameter than its stroke length, giving a bore/stroke ratio greater than 1:1. An oversquare engine allows for more and larger valves in the head of the cylinder, higher possible rpm by lowering maximum piston speed, and lower crank stress due to the lower ...
The engine had MPFI (multi-port fuel injection), which gave slightly more power and better fuel economy, and two valves per cylinder. The engine had a bore and stroke of 4 + 1 ⁄ 4 in × 4 in (108.0 mm × 101.6 mm), producing 290 hp (216 kW) at 4000 rpm and 410 lb⋅ft (556 N⋅m) at 3200 rpm. L29 applications:
Bore Stroke Displacement Power Rating Production Run Dry Weight 3AA1 This engine shares the bore and stroke of the C190 four-cylinder diesel and 2AA1 two-cylinder. The Bosch PES-A fuel pump is the same as the one used on the 3AA1, 3AB1, C220, and C240 engines. [9] 86 mm (3.4 in) 84 mm (3.3 in)
The first engine in the series is designated CB18, a 1.8 litre dual overhead cam 16-valve engine featuring dual AVCS with gasoline direct injection and a turbocharger. Bore and stroke are 80.6 mm × 88.0 mm (3.17 in × 3.46 in), respectively, and the compression ratio is 10.4:1.
1962 – The block's cylinder wall casting was revised to allow four-inch bores, and the 327-cubic-inch version of the engine, using this bore diameter and increased stroke, was introduced. 1967 - The oil filter mounting received an adapter and machining to allow the use of spin-on filters; canister mounting was possible by removing the adapter.
