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 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 engine.
Engine block. Block of a modern V6 diesel engine. The large holes are the cylinders, the small round orifices are mounting holes, and the small oval orifices adjacent to the cylinders are coolant or oil ducts. In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block ...
Fuel type. Petrol. Chronology. Predecessor. BMW M78. Successor. BMW M335. The BMW M328 is an overhead valve straight-six petrol internal combustion engine which was produced from 1936 to 1940. It was a high-performance development of the BMW M78 engine that was produced alongside the M78.
RR layout. In automotive design, an RR, or rear-engine, rear-wheel-drive layout places both the engine and drive wheels at the rear of the vehicle. In contrast to the RMR layout, the center of mass of the engine is between the rear axle and the rear bumper. Although very common in transit buses and coaches due to the elimination of the drive ...
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the ...
The TVR Speed Twelve engine is the name of a V12 engine manufactured by TVR for use in the TVR Speed 12 race car, and later the TVR Cerbera Speed Twelve road car. [2] The engine was developed by essentially joining two Speed Six engine blocks to a common crankshaft. However it featured a revised cylinder head design with bucket valve actuation ...
Monobloc engine. A monobloc or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later. This has the advantages of improving mechanical stiffness, and improving the ...
Front-engine, four-wheel-drive layout. In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road ...
