The 1.5 L 1A was produced between 1978 and 1980. [6] All variants were belt-driven 8-valve counter-flow SOHC engines with a single, twin-barrel downdraft carburetor.It used Toyota's Turbulence Generating Pot (TGP) lean combustion system to meet Japanese emissions standards at the time with only an oxidation (2-way) catalyst.

A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
The '151E' engine used 4 valves per cylinder. [citation needed] The '100E' engine used twin spark plugs with 2 valves per cylinder but was used mainly by a Toyota works team. [citation needed] Italy Nova Corporation produced a 2.0 L engine based on the 2T-G that was used in most of the world F3 cars for a long time. [16] [17] [18] [19]
An isolation valve is a valve in a fluid handling system that stops the flow of process media to a given location, usually for maintenance or safety purposes. [1] They can also be used to provide flow logic (selecting one flow path versus another), and to connect external equipment to a system. [ 2 ]
The eight-valve overhead valve 1.2 L (1,166 cc) 3K was produced from 1969 through 1977. Cylinder bore and stroke was 75 mm × 66 mm (2.95 in × 2.60 in). The 1969 through 1975 3K-B was a twin-carburetor version. The California-spec 3K-C (1977–1979) and 3K-H were other available versions. Applications
A relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in a tractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of the vehicle ...
LNER Class V2 4771 Green Arrow.Note Gresley conjugated valve gear located ahead of the piston valves, driven from the valve spindles. The Gresley conjugated valve gear is a valve gear for steam locomotives designed by Sir Nigel Gresley, chief mechanical engineer of the LNER, assisted by Harold Holcroft.
Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, a flexible diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic , metal or other materials depending on the intended use.
