The Nissan TD series is a series of diesel engines manufactured by Nissan. All TD-series engines are inline engines; most versions are four-cylinders aside from the six-cylinder TD42. They have cast iron blocks and crossflow heads; the combustion chamber design is a swirl-chamber design with indirect injection and a gear driven cam. The valves are pushrod-actuated, and the engine has two valves per cylinder; the camshaft is driven by a set of gears. Of a simple, somewhat old-fashioned construction, the engines are generally durable if not very powerful.
