Similar to B series, the K-series car engines have two short blocks with the same design; the only difference between them being the deck height. K20 uses the short block with a deck height of 212 mm (8.3 in) where K23 and K24 block has a deck height of 231.5 mm (9.1 in). [1] A cylinder head from a Honda K20Z3.
Valve Train OHV Cam-in-block; four-valve-per-cylinder Carburetion Twin Keihin 40.0 mm butterfly with manual choke Ignition Triple-wound stator, low speed, high speed, and charging, transistor ignition
It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a " drive by wire " throttle system which is computer controlled to reduce pumping losses and create a smooth torque ...
The Type S runs with the improved iDTEC 2.2 diesel engine which now has 180 PS (132 kW; 178 hp). The increased power is due to a modified turbo, cylinder head and larger intercooler. Also, the radiator has grown in size. In addition, the clutch has been updated to handle the increased torque of 380 Nm over the standard 350 Nm.
In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins. In more modern overhead valve and overhead camshaft engines, the head is a more complicated metal block that also contains the inlet and exhaust passages, and often coolant passages, Valvetrain components, and fuel injectors.
In engine technology, a reverse-flow or non-crossflow cylinder head is one that locates the intake and exhaust ports on the same side of the engine. The gases can be thought to enter the cylinder head and then change direction to exit the head. This is in contrast to the crossflow cylinder head design.
A crossflow T-head sidevalve engine The usual L-head arrangement Pop-up pistons may be used to increase compression ratio Flathead with Ricardo's turbulent head. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve ...
