Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...
The first Y-block on Ford automobiles and F100 trucks was the 239 cu in (3,910 cc) version as released in 1954 with EBU casting numbers. The Y-block was the same displacement as the old Ford Flathead V8 that it replaced but with a bigger bore and a shorter stroke (3.5 x 3.1 in).
The first year had unique chrome valve covers with Chevrolet stamped into them without an engine displacement decal pad. In 1968, the engine had the chrome covers, but without the Chevrolet name, connected to a PCV valve and a chrome 14 in × 3 in (355.6 mm × 76.2 mm) drop-base open-element air cleaner assembly fitted with a crankcase breather ...
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 ...
Speed has dropped out of the equation, and the only variables are the torque and displacement volume. Since the range of maximum brake mean effective pressures for good engine designs is well established, we now have a displacement-independent measure of the torque-producing capacity of an engine design – a specific torque of sorts.
The 1.2-litre engine is called Type 122 and has a displacement of 1,192 cc (72.7 cu in). [3] As industrial engine, its rated power is 22.8 kW (31 PS; 31 bhp) at 3000 min −1 without a governor , the highest torque 81.4 N⋅m (60 lbf⋅ft) at 2000 min −1 .
The Holden straight-six motor is a series of straight-six engines that were produced by General Motors Holden at their Port Melbourne plant between 1948 and 1986. The initial Grey motor was so dubbed because of the colour of the cylinder block, later motors came in the form of a Red, Blue, Black, and the four-cylinder Starfire engine.
The 2Y engine is an OHV, eight valve construction just like the 1Y. It shares that engine's 86 mm (3.39 in) bore, but stroke is increased to 78 mm (3.07 in) for a displacement of 1.8 litres (1,812 cc). There are also 2Y-J and 2Y-U engines with differing emissions control equipment. OHV, eight valves; Displacement: 1.8 L (1,812 cc)
