Standard on every NPR-HD, NQR and NRR is the Isuzu 4HK1-TC engine known worldwide for its power and ruggedness, and improved to deliver even more performance, economy and reliability.

Its high-pressure common-rail fuel injection system wrings the most energy out of every drop of fuel, and its intercooled, variable-geometry turbocharger provides excellent response over the engine's entire RPM range. Together, these features help the 4JJ1-TC produce 150 horsepower and 282 lbs.-ft. of torque.

The 4HK1-TC is now equipped with electronic high-pressure common-rail direct injection and a water-cooled EGR system to achieve unprecedented performance -- 210 horsepower for trucks equipped with the automatic transmission, and 190 horsepower for manual-transmission models.

At Isuzu, improvements in power never come at the expense of reliability, durability, or fuel economy. The 4HK1-TC engine can still run up to 10,000 miles between oil changes reducing maintenance costs and downtime and boasts an astonishing B10 durability rating of 310,000 miles. And despite the increased power and lower emissions, Isuzu N-Series trucks equipped with the 4HK1-TC engine will achieve approximately 8% better fuel economy than the models they replace.
