Toyota Motor Corporation's M family of engines were a longitudinally mounted straight-6 engine design. They were used from the 1960s through the 1990s. All M family engines were OHC designs. While the M family was born with a chain-driven single camshaft it evolved into a belt drive DOHC system after 1980. All M family engines used a cast-iron block with an aluminum cylinder head, and were built at the Toyota Kamigo plant in Toyota City, Japan. The Japanese market only M-E was the first Toyota engine to be equipped with fuel injection (at the same time as the 4-cylinder 18R-E). The 4M-E was the first Toyota engine to be equipped with fuel injection for non-Japanese markets. The M family were Toyota's most prestigious engines (apart from the uncommon ''V family'' V8) for 30 years. They were commonly found on the large Toyota Crown, Mark II, and Supra models. ==M== The first M was a 2.0 L (1988 cc) version produced from 1965 through 1988. It was a 2-valve SOHC engine. Cylinder bore and stroke was square at 75 mm (2.95 in). Output was at 5200 to 5600 rpm, depending on specifications and model year. Typical torque is 116 lb·ft (157 Nm) at 3800 rpm. An LPG version, the M-LPG, was produced from 1966 through 1988. The "M-C" engine, for commercial vehicles such as the Crown Van produces . Twin SU sidedraft carburetors pushed output for the M-B and M-D to at 5800 rpm. Anti emissions versions, the M-U, M-U LPG and M-EU, replaced the M, M-LPG and M-E on the Japanese market in mid 1976. The emissions system was called TTC (Toyota Total Clean), with a "-C" to denote the installation of a catalytic converter.
