Fuel Injection System - 4-CYL Diesel: Description
The 2.0L engine uses a Nippondenso mechanical high pressure fuel injection pump. The injection pump meters an exact amount of fuel to fuel injectors, as required by engine operating conditions.
The fuel injection pump is belt-driven by the rear camshaft timing belt. High pressure fuel lines deliver fuel from the injection pump to injection nozzles mounted in the cylinder head.
A fuel filter and conditioner is located in the fuel line between fuel tank and injection pump. A quick start and afterglow system are used to assist in starting when engine is cold.
