Common-rail fuel injection system
Electronic control precisely injects fuel at extremely high pressure in 1/1000 second units and determines optimal injection amounts, reducing NOx and particulate matter (PM).
(4JJ1-TC, 4HK1-TCN)

16-valve DOHC
Valve operation is accurately timed even at high rpm, increasing air intake and discharge from cylinders, thereby raising intake and exhaust efficiency.
These optimal combustion conditions reduce PM and black smoke while raising fuel economy.

Manual transmission
Powerful yet economical and easy to handle. Reliability and durability you can count on.
Trucks equipped with the 4HK1-TCN powerplant come with a six-speed transmission except NPS models.
