E engine car

The E-series was a line of inline 4-cylinder automobile engines from Honda. These engines were used in the popular Honda Civic, Accord, and Prelude cars in the 1970s and 1980s. One notable technology was CVCC, introduced with this family, which allowed the company to meet high emissions standards without using a catalytic converter.

There were two different EK engines, until 1981 the heads used a 2 port exhaust design. After 1981 the head used a 4 port exhaust design. Both had a 12 valve head, 8 main valves and 4 CVCC, or auxiliary valves. Both displaced 1.8 L (1751 cc). 2-port output was 72 hp (54 kW) @ 4500 rpm and 94 ft·lbf (127 N m) @ 3000 rpm, while the 4 port head raised this to 75 hp (56 kW) @ 4500 rpm and 96 ft·lbf (130 N m) @ 3000 rpm.
