MCA-Jet was a simpler system that sent the same air/fuel mixture to all intake and MCA-Jet valves. Each MCA-Jet valve is quite small and may be prone to carbon build-up, causing the MCA-Jet valve(s) to stick open. If a Mitsubishi-designed engine has low compression, the MCA-Jet valve(s) could be the cause. Each MCA-Jet valve and valve seat are ...
Those with the later, cleaner yet, "MCA-Jet" system were called G32B. Later, the G32B also came in a fuel injected , turbocharged model. For competition, a version of the 4G32 engine was made with a DOHC eight-valve cylinder head, and fitted with two twin-choke 40 mm (1.6 in) Solex sidedraft carburettors.
The SOHC eight-valve 4G54 (also known as the G54B) displaces 2.6 L (2,555 cc), with bore & stroke at 91.1 mm × 98 mm (3.59 in × 3.86 in). The G54B for the US market had a cylinder head with additional jet valves to improve emissions (MCA-Jet system).
The Chrysler version features fracture-split forged powder metal connecting rods. The DOHC and SOHC 16-valve 4G64 are interference engines , while the SOHC 8-valve 4G64 is a non interference engine. From March 1996 an LPG version with 115 hp (86 kW; 117 PS) at 5,000 rpm was available in the Mitsubishi Canter .
The Mitsubishi Vulcan engine, identified by the code 2G2, is an iron-block twin cylinder engine with three main bearings, built by Mitsubishi Motors for kei car class vehicles from September 1972. It was an overhead camshaft design, and superseded the older two-stroke 2G1 series. The 2G2 was in turn replaced by the Multi-valve 3G8 three ...
All jet engines require high temperature gas for good efficiency, typically achieved by combusting hydrocarbon or hydrogen fuel. Combustion temperatures can be as high as 3500K (5841F) in rockets, far above the melting point of most materials, but normal airbreathing jet engines use rather lower temperatures.
Closing the valve too quickly while trying to reduce power output could cause a lean die-out, where the airflow through the engine blows the flame out of the combustion chamber and extinguishes it. Adding fuel too quickly to increase power can damage the turbines due to excessive heat, or the sudden rise in combustion chamber pressure may cause ...
The engine is an analogue of the Mitsubishi G15B in terms of the engine mechanical specifications except for the valve timing. The G13B is also equipped with jet valves and jet springs. SPECIFICATIONS: Total displacement: 1.5 L (1,468 cc) Bore x Stroke: 75.5 mm × 82 mm (2.97 in × 3.23 in) Compression Ratio: 9.4:1
