An electronic engine control unit has an engine map stored in its ROM and uses it as well as sensor data to determine how much fuel has to be injected, and when the fuel has to be injected. Engines with manifold injection, and an electronic engine control unit are often referred to as engines with electronic fuel injection (EFI).
The name stems from an old Iranian name, meaning "child of the sun." The Mehran received minor facelifts in 1998 and again in 2004. The Mehran [2] was available in VX, Euro-II or VXR equipment levels. It had again received a mild facelift with an asymmetric grille at the same time as the introduction of the EFi engine in 2012. Production ended ...
The first four-stroke direct-injection petrol engine for a passenger car was released the following year, in the Mercedes-Benz 300SL sports car. [41] However the engine suffered lubrication problems due to petrol diluting the engine oil, [42] [43] and subsequent Mercedes-Benz engines switched to a manifold injection design. Likewise, most ...
The Toyota RZ engine family is a straight-four piston engine series built in Japan. The RZ series uses a cast-iron engine block and aluminum SOHC or DOHC cylinder heads . It has electronic fuel injection (EFI), 2 or 4 valves per cylinder and features forged steel connecting rods .
The 3S-FE is fitted with EFI. The 3S-FE engine is fitted with a cast iron crankshaft, whereas the 3S-GE/GELU engines have forged crankshafts. [11] The 3S-FSE was a direct injection engine with Toyota D4 system. A cam driven high pressure fuel pump is at the #4 end of the head. This engine was only released in Japan, and installed in the Camry ...
The bore and stroke is 92 mm × 92 mm (3.62 in × 3.62 in). Due to the EFI system, the 2L-TE develops significantly more torque than its predecessor. The redline of this engine is at 4800 rpm, the compression ratio is 20.0:1. [59] The 2L-TE was largely replaced by the KZ engine in 1993, although it continued to be used in some models until 2000.
An EFI version of the 4.1-litre engine was introduced in February 1983, [2] incorporating Bosch Jetronic LE fuel injection. [13] While it was intended to replace the now-defunct 4.9 L (302 cu in) V8, the 4.1 EFI engine initially produced only 111 kW (149 hp) and 325 N⋅m (240 ft⋅lb), a significant reduction from the 140 kW (188 hp) and 344 N ...
The turbocharged engine featured a specially designed cam profile (0.240", comparable to the 1.6 HO and EFI camshafts), a Ford Performance/SVO modified head (comparable to European 1.6s), the EFI intake manifold, a unique cast exhaust manifold, low-dome pistons, and Ford's top-of-the-line EFI and ECU. These engines only appeared in the 1984 ...
