Nissan CA engine

From Wikipedia, the free encyclopedia.

The CA engine is a 1.6 L to 2.0 L Inline-4 piston engine from Nissan designed for a variety of small Nissan vehicles. It is an iron block, aluminum head design. Earlier versions featured SOHC and 8 valves for mid-range power. Later versions featured DOHC with 16 valves for increased high RPM efficiency and smoother power delivery.

The CA series engine was the workhorse of the 1980's and was a bulletproof little engine. The power ratings were heavily choked by emissions regulations and Nissan's desire for high gas mileage. The CA design ended in 1990 with the penultimate CA engine, the CA18DET.
