SOHC design (for a 1973 Triumph Dolomite Sprint) . The oldest configuration of overhead camshaft engine is the single overhead camshaft (SOHC) design. [1] A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft and a V engine or flat engine has a total of two camshafts (one for each cylinder bank).
1979–1986 D20 — 2.0 L (1,986 cc) inline five-cylinder SOHC, 50 kW (68 PS) — Volvo 240 (for Finland and possibly other export markets)
Nissan does not have a letter designation for the SOHC configuration so the camshaft configuration type is assumed as SOHC if no letter is present. Another example is the MR16DDT engine, which has feature designations that describe an engine with dual overhead camshafts, direct cylinder fuel injection and a single turbocharger.
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
With low-rise, medium-rise, high-rise, tunnel-port, or SOHC intake manifolds. The low-rise intake, designed to fit under a low hoodline, was the first. The high-rise intake required a hood bubble for clearance.
The SOHC EJ Subaru boxer engines were non-interference engines through 1995, run by a single timing belt driving both cams (both sides of the engine) and the water pump. Because they are non-interference engines, if the timing belt fails, the engine of the models up to 1995 will not be damaged.

The engine was upgraded to a four-stroke SOHC in 1973 to meet Japanese Government emission regulations, using the SEEC emissions system (later SEEC-T), with an alloy block and head. [ 2 ] The ( Japanese : Subaru EK series ) was used from 1958 until 1989 in most Kei car models.
