The 1HD-FT is a 4.2 L (4164 cc) straight-6 24 valve SOHC turbocharged diesel engine of direct injection design. Bore is 94 mm and stroke is 100 mm, 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 168 hp (125 kW) ECE at 3600 rpm with 380 N·m (280 ft-lb) of torque ECE at 2500 rpm.
