• Fuel Injection

  Fuel injection systems offer greater fuel efficiency and engine performance. The Engine Control Unit calculates air/fuel ratios according to how much you press the accelerator, and these ratios are then communicated to the fuel injectors. A high-pressure spray of fuel is then injected to the cylinder, powering the engine.

• Reservoir

  A reservoir is a receptacle that holds liquid until it is needed, like the coolant reservoir that feeds into the radiator.

• Manifold Heat Control Valve

  The manifold heat control valve helps the car idle smoothly and prevents stalling in cold weather. It ensures the petrol doesn’t condense back into liquid form by forcing hot exhaust gases up to the intake manifold and carburettor to warm the air-fuel mixture.
