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.

The CVCC ED1 was on the Ward's 10 Best Engines of the 20th century list.

[edit] EB

The EB series displaced 1.2 L (1170 cc, 71 cu in) and was an SOHC 8-valve design with a 2 barrel carburetor. Output for the EB1 was 50 bhp (37 kW) @ 5000 rpm and 59 ft·lbf (80 N·m) @ 3000 rpm, and this was up to 63 bhp (47 kW) @ 5000 rpm and 77 ft·lbf (104 N·m) @ 3000 rpm for the EB2 and EB3.

[edit] EC

The EC series engine is used in the gasoline/electric Honda Insight Hybrid. This 3 cylinder Engine is a SOHC 12 valve sized 1 L (995 cc, 61 cu in)-DK. The ECA1 produces 68 hp (50 kW) @ 5700 rpm and 67 ft·lbf (N·m) of torque @ 4800. The ECA1 motor is assisted in various circumstances by a 10 kW permanent magnet DC electric motor adding 8 horsepower and 16 ft·lbf torque throughout the entire RPM range. It is completely unrelated to the rest of the E-series engines.

[edit] EK

There were 2 different EK engines, until late 1979 the heads used a two port exhaust design. On the 1979 through 1981 EK1 the head used a four port exhaust design. For 1982 and 1983, the intake and exhaust port layout was changed, and head bolt spacing was changed to allow better flow. EK motors were CVCC and were 8 valve motors with 4 additional auxiliary intake valves. Both displaced 1.8 L (1751 cc, 107 cu in). 2-port output was 72 hp (54 kW) @ 4500 rpm and 94 ft·lbf (127 N·m) @ 3000 rpm, while the original 4-port head raised this to 75 hp (56 kW) @ 4500 rpm and 96 ft·lbf (130 N·m) @ 3000 rpm. The revised 4-port had another slight horsepower increase.

[edit] EW

The final E-family engine was the EW. Displacing 1.5 L (1488 cc, 91 cu in), the EWs were SOHC 12-valve engines. Early 3 barrel EW1s produced between 58 and 76  hp (43 and 57 kW) and 80 to 84 ft·lbf (108 to 114 N·m). The fuel injected EW3 and EW4 produced 91 hp (68 kW) @ 5500 rpm and 93 ft·lbf (126 N·m) @ 4500 rpm. The "EW" name was replaced by the, commonly known, Honda "D series." The EW(1,2,3,4, and 5) received a new name as well as engine stamp placement on the front of the engine like the "modern D series" (aka 1988 and newer) in 1987 as the D15A(1,2,3,4, and 5).

• EW5
  • similar to the EW1, Fuel injected CVCC 12Valve 4 Aux valves. A third throttle plate in the throttle body supplied intake air to a 5th injector which powered the CVCC ports, The rated power is different between the Civic and the CR-X the Civic makes 100 PS (99 hp) 5800RPM 13.2 kg/m (9.7 lb·ft) torque @ 4000RPM, the CR-X made 110 PS (110 hp) 5800RPM 13.8 kg/m (10.2 lb·ft) torque @ 4500RPM. Differences in power are largely down to a more efficient exhaust system on the CR-X it used a factory cast iron 4-2-1 extractor went through a catalytic converter further down the exhaust system and had twin exit tail pipes. The Civic had a short 4-1 design into a catalytic converter and single pipe exit. There was a revised intake manifold for vehicles produced in 1986 and 1987. The EW5 was not available in the North American markets, only Japan It came in the following models 1.5i CR-X, 25i 3DR Civic, Ballade CRi 4DR Sedan.
