4HK1 (Euro II)


DOC (Diesel Oxidation Catalyst)
The unburnt particles, primarily hydrocarbons, within the exhaust PM from the engine are converted into H2O, CO2, and other harmless substances.
This greatly reduces the amount of harmful substances released.

Cooled EGR
The air released by combustion is cooled and returned to the intake, and by reducing the concentration of oxygen, the heat of combustion is curtailed. This effectively reduces NOx.

lntercooled turbo
lntercooled turbo The turbocharger supercharges with excellent efficiency. And a high-performance intercooler is utilized for high air-intake cooling effects.
This improves the low-torque performance and acceleration, and helps raise the fuel economy.

Common rail fuel injection system
Electronic control precisely injects fuel at extremely high pressure and determines optimal injection amounts, reducing NOx and particulate matter (PM).
(4JH1, 4JJ1, 4HL1, 4HK1)

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. (4JJ1)

Manual transmission
Powerful yet economical and easy to handle.
Reliability and durability you can count on.
Trucks equipped with the 4HK1 and 4HL1 powerplants come with a six-speed transmission except NPS models.
