Although Japanese car manufacturers typically purchased diesel engines for their cars before 2003, Honda began production of its own N22A1 diesel engine named the 2.2 CTDi in the same year. The engine was a popular choice in the Civic VIII and Accord VII, generating 140 hp and 250 lb-ft of torque.
The four-cylinder, 16-valve engine has a chain-driven camshaft, common rail fuel injection system with Bosch injectors, variable geometry Garrett GTA1752LV turbine, and a double mass flywheel. The engine complies with the Euro 4 emissions standard. The engine has a rated durability of 600,000 kilometers and has an approximate engine life expectancy (before serious repairs) of 220,000 to 370,000 kilometers. A realistic engine life expectancy depends on the regularity of maintenance and the quality of the materials used.
However, even a well-maintained CTDi engine can have problems, though such issues are typical of diesel engines. The supercharger is subject to premature failure of shaft bearings and the EGR valve is prone to clogging, especially in cars driven mostly in city traffic. These issues can result in a decrease in power, uneven engine performance, and excessive smoke. Installed in a Honda CR-V, the 2.2 CTDi Engine seems a bit underpowered. Car and Driver tests showed the compact SUV accelerating to 60 mph in a lethargic 9.4-seconds but is only 0.3 seconds slower than the category average. Performance improves once the turbo spins up and the fuel efficiency is rated at 28 mpg while the highest recorded average for a gas-fueled CR-V is 22 mpg.
