1HD-FT
The 1HD-FT is a Script error: No such module "convert". straight-6 24 valve SOHC turbocharged direct injection diesel engine. Bore and stroke is Script error: No such module "convert"., with a compression ratio of 18.6:1. Known as the "multivalve" it has 4 valves per cylinder (2 inlet, 2 exhaust), central vertically mounted injector, and no glow plugs but rather an intake glow screen heater (like the later electronic 1HD-FTE below). The 4 valves per cylinder are actuated by the SOHC, by using bridges so each rocker actuates a pair of valves. Output is Script error: No such module "convert". ECE at 3,600 rpm with Script error: No such module "convert". of torque ECE at 2,500 rpm. However, marinized version of 1HD (sold as Yamaha ME and Yanmar 6LP) have an output of Script error: No such module "convert". on Yanmar 6LP and Script error: No such module "convert"., Script error: No such module "convert". or Script error: No such module "convert". on Yamaha ME.[2][3][4][5]

1HD-FTE
The 1HD-FTE is a Script error: No such module "convert". straight-6 24 valve turbocharged diesel engine. Bore and stroke is Script error: No such module "convert"., with a compression ratio of 18.8:1. Output is Script error: No such module "convert". at 3,400 rpm with Script error: No such module "convert". of torque at 1,400 rpm. The fuel system is direct injection, and adopts the electronic fuel injection (EFI) system. Redline of this engine is at 4200 rpm.
The 4 valves per cylinder are actuated by the SOHC, by using bridges so each rocker actuates a pair of valves.
The version with intercooler as fitted to HDJ100 station wagons has Script error: No such module "convert". at 3400 rpm with Script error: No such module "convert". of torque at 1200-3200 rpm with a redline reaching 4200 rpm. A lower output Script error: No such module "convert". non-intercooled version powers HDJ78 Troop Carrier and HDJ79 Utility versions.
Also some of the HDB50 and HDB51 Coasters are fitted with this 1HD-FTE engine.
