Although it displaces 134 cu. in, the 2.2-liter OHV is still commonly referred to as the GM 122 today, and has been reputed for its simplicity, reliability, and ease of maintenance in the J-body cars and S-series trucks, and a few L-body cars. The 2003 model LN2 is equipped with secondary air injection. [1] Applications: 1993–1996 Buick Century
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

For 1980 the Iron Duke engine was redesigned to be mounted transversely, to suit the new front-drive General Motors "X-body" cars. The bellhousing bolt pattern was revised to match that of the new 60° V6 engine. 1982 AMC Spirit with Iron Duke. GM also began selling the engine to American Motors Corporation (AMC
It featured the same multiport fuel injection intake manifolds and throttle body as the LH0, and produced 205 hp (153 kW) at 5200 rpm and 225 lb⋅ft (305 N⋅m) of torque at 2100 rpm. Around 3,700 engines were produced each year. This engine had a block with more nickel content and hardened internals. Applications:
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
There is essentially no difference in efficiency between the technique of bypassing the throttle butterfly and operating the butterfly itself. The IAC allows the ECU to maintain minimum RPM irrespective of changes in engine load, sometimes referred to as anti-stall feature. Thus the driver can more easily move the car from stand-still by merely ...
In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1981. Available in a wide range of cubic capacities ranging from 1598 to 2405 cc, it simultaneously replaced the Opel CIH and Vauxhall Slant-4 engines, and was GM Europe's core mid-sized powerplant design for much of the 1980s, and provided the basis for the later Ecotec series of ...
