Some cars are produced with block heaters from the factory, while others are fitted with block heaters as an aftermarket add-on. [3] The most common type of block heater is an electric heating element in the engine block , which is connected through a power cord often routed through the vehicle's grille.
The FB has an all new block and head featuring dual overhead cams with intake and exhaust variable valve timing (which Subaru designates as AVCS, standing for Active Valve Control System), and a timing chain that replaced the timing belt. Moving to chain-driven cams is said to allow the valves to be placed at a more narrow angle to each other ...
The Subaru FA engine is a gasoline boxer-4 engine used in Subaru and Toyota automobiles. It is a derivative of the FB engine, with efforts to reduce weight while maintaining durability as the main design goals.
Cylinder block material: Cast iron: Cylinder head material: Cast iron: Valvetrain: Cam-in-block 2 (B-Series) or 4 (ISB, QSB) valves/cylinder: Compression ratio: 17.2:1, 17.3:1, 17.5:1, 19:1: Combustion; Turbocharger: Holset Engineering (variable) Fuel system: Common rail high pressure direct injection, symmetrical combustion chamber with 7-hole ...
The Polyspheric or Poly engines were V8 engines produced by Chrysler from 1955 to 1958 as lower-cost alternatives to the Hemi engines. [1] These engines were based on the Hemi engines, using the same blocks and crankshaft parts, but completely different cylinder heads, pushrods, exhaust manifolds and pistons.
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 RB26DETT engine block is made from cast iron, while the cylinder head is made from aluminium alloy, which contains DOHC 4 valves per cylinder (24 valves in total) setup. The intake of the RB26DETT varies from other RB-series motors in that it has six individual (3 sets of 2 throttle assemblies that are siamesed together) instead of a single ...
1937 diagram of engine cooling entirely by thermosiphon circulation. Some early cars, motor vehicles, and engine-powered farm and industrial equipment used thermosiphon circulation to move cooling water between their cylinder block and radiator. This method of water circulation depends on keeping enough cool air moving past the radiator to ...
