Honda E engine

The E-series was a line of inline four-cylinder automobile engines designed and built by Honda for use in their cars in the 1970s and 1980s. These engines were notable for the use of CVCC technology, introduced in the ED1 engine in the 1975 Civic, which met 1970s emissions standards without using a catalytic converter.

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

EA

 * Also see the Japanese Wikipedia entry

The EA-series is a water-cooled 356 cc inline two-cylinder engine replacing the N360's air-cooled 354 cc engine. An SOHC design with a timing belt (replacing the chain used in the N360 engine), the EA was first seen in the 1971 Honda Life. This engine was derived from the air-cooled engine in the Honda CB450 and was adapted for water-cooled application. The displacement was reduced to be in compliance with Japanese kei car legislation that stipulated maximum engine displacement. Bore and stroke were 67x50.6 mm. A version producing 30 PS at 8,000 rpm was installed in the Honda Life, while the Honda Z and the Honda Life Touring (introduced in May 1972) received a twin-carb model with 36 PS at a heady 9,000 rpm.

EH
The water-cooled SOHC two-cylinder EH was first seen installed in the first generation Honda Acty truck introduced in July 1977, and later in the 1985 Honda Today. It was based on one bank of cylinders from the horizontally opposed four used on the Honda Gold Wing GL1000 motorcycle, with which it shared the 72 mm bore. The horsepower rating of the 545 cc 72x67 mm engine was 28 PS at 5,500 rpm, and 4.2 kgm at 4,000 rpm. When installed in the Today, max power was raised to 31 PS at the same revs, and torque at 4.4 kgm, with a compression ratio of 9.5:1.

ER
The long-stroke ER four-cylinder engine,
 * sold as a 12-valve CVCC-II in Japan and as a simple eight-valve unit in Europe and Asia,
 * was only used in the AA/VF/FA series City/Jazz from 1981 until 1986.
 * It was available as a normally aspirated carburated version or with Honda's own PGM-FI fuel injection as one of a very few turbocharged engines built by Honda.
 * The Japanese market CVCC engine was also known as COMBAX, an acronym of COMpact Blazing-combustion AXiom. The E-series were tuned for economy, with higher gearing and later on with computer-controlled variable lean burn.
 * As of March 1985, the naturally aspirated ER engines gained composite conrods (a world first in a production car), lighter and stronger these helped further reduce fuel consumption.

The lower powered engines in the commercial "Pro" series had a lower compression, a mechanically timed ignition rather than the breakerless setup found in the passenger cars, and a manual choke. The ER had five crankshaft bearings and the overhead camshaft was driven by a cogged belt.

Carburetor versions used either a single or 2bbl downdraft Keihin. The turbocharger in the Turbo and Turbo II was developed together with IHI, the Turbo II being equipped with an intercooler and a computer-controlled wastegate.

ES
The ES displaced 1829 cc. All ES engines were SOHC 12-valve engines. The ES1 used dual sidedraft carburetors to produce 102 PS @ 5500 rpm and 14.4 kgm @ 4000 rpm. The ES2 replaced this with a standard 3 barrel carburetor for 87 PS @ 5800 rpm and 13.7 kgm @ 3500 rpm. Finally, the ES3 used PGM-FI for 102 PS @ 5800 rpm and 14.9 kgm @ 2500 rpm.

The ET2 with dual sidedraft carburetors and 4-2-1 exhaust manifold produced 100 PS at 5,500 rpm and 14.4 kgm at 4,000 rpm. JDM versions included a triple-barrel carburetted version for the Accord (110 PS at 5,800 rpm) and one with Honda PGM-FI which produced 130 PS at 5,800 rpm.

The EV displaced 1342 cc 74mm bore, 78mm stroke and was an SOHC 12-valve design. 3 barrel carburetors produced 61 PS at 5,500 rpm and 10.1 kgm at 3,500 rpm for the US market. The JDM version, featuring 12 valves and auxiliary CVCC valves, produced 80 PS at 6,000 rpm and 11.3 kgm at 3,500 rpm. It was available in all bodystyles of the third generation Honda Civic.

EW
The final E-family engine was the EW, presented along with the all new third generation Honda Civic in September 1983. Displacing 1488 cc, the EWs were SOHC 12-valve engines. Early 3 barrel EW1s produced from 58 to 76 hp and 11 to 11.6 kgm. The fuel injected EW3 and EW4 produced 92 PS at 5,500 rpm and 12.8 kgm at 4,500 rpm. The "EW" name was replaced by the Honda D15 series, with the EW (1, 2, 3, 4, and 5) renamed to D15A (1, 2, 3, 4, and 5) in 1987. It also received a new engine stamp placement on the front of the engine like the "modern D series" (1988+).

 * similar to the EW1, Fuel injected CVCC 12-Valve 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 at 5800 rpm and 13.2 kgm torque at 4000 rpm, the CR-X made 110 PS at 5800 rpm and 13.8 kgm torque at 4500 rpm. 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 only available in Japan. It came in the following models: CR-X 1.5i, Civic 25i Hatchback, Ballade CRi Sedan.

ZA
The ZA1 and ZA2 are anomalously named, but closely related to the 1.3-litre EV. With a shorter stroke but the same bore 74x69 mm, this 1187 cc shared most of the EV's characteristics. It was only sold in the third generation Civic in European and various smaller markets where the taxation structure suited this version. The high octane version produces 62 PS at 6000 rpm and 9.0 kgm at 4000 rpm. There was also a low-octane model, producing 55 PS at 6000 rpm.
