Single-point injection was used extensively on American-made passenger cars and light trucks during 1980–1995, and in some European cars in the early and mid-1990s. In the US, the G10 engine in the 2000 Chevrolet Metro became the last engine available on an American-sold vehicle to use throttle body injection.
The L03 produced 170 hp (127 kW) at 4400 rpm and 255 lb⋅ft (346 N⋅m) of torque at 2400 rpm in 1993–1995 GM trucks. This engine used the TBI throttle body fuel injection, which was a hybrid between EFI and carburetor technology. It used an EFI system with electronically controlled injectors, which were mated to a twin barrel "carburetor" body.
In the US, this kind of single-point injection was marketed as 'throttle body injection' (TBI, by GM), or 'central fuel injection' (CFI, by Ford). Mono-Jetronic is different from all other known single-point systems, in that it only relies on a throttle position sensor for judging the engine load.
For the 1990 model year, GM replaced the 2.0-liter engine with a stroked version displacing 2.2 liters and using throttle-body fuel injection (TBI). Commonly called the 2.2, it produced 95 hp (71 kW) and 120 lb⋅ft (163 N⋅m) of torque. Applications: 1990–1991 Chevrolet Beretta; 1990–1991 Chevrolet Cavalier; 1990–1991 Chevrolet Corsica
For 1991, the 700R4 was renamed to the 4L60. The TBI (throttle body injection) system used on the Blazer's standard 5.7 liter V8 had longer throttle shaft bearings, new throttle return springs, and improved fuel mixture distribution. The 5.7 liter V8 also had new heavy-duty intake valves and powdered metal camshaft sprockets.
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).
