Ignition Coils One coil per cylinder allows the coil a longer time to accumulate a charge between sparks, and therefore a higher energy spark. This is a very popular design and is easily adaptable to different engine layouts.
The plug top coil is mounted directly on the spark plug and each unit is powered separately to allow the engine to independently manage each coil. Plug top coils are also used where a spark plug well diameter is too small to allow for a pencil coil (22mm).
Are 4 or 2 coils mounted together that fit directly on top of the engine. In the four coil configuration they operate in a similar way to pencil and plug top coils. In the 2 coil configuration they operate a wasted spark system where each coil links to a pair of cylinders, normally 1- 4 and 2- 3. This means that one plug will be sparking during the end of the exhaust stroke while the other plug fires at the usual time at the end of the compression stroke.
These are near plug coils which normally operate the wasted spark system of 1 coil to 2 cylinders. The pack design can offer one of the highest energy densities to enable a mass reduction of up to 40 percent compared with conventional ignition coils.

The air mass meter is used to determine the air mass that is being delivered to the engine. This signal allows the ECU to adapt the fuel injection accordingly. In modern Diesel applications the air mass sensor is additionally needed to control and monitor the EGR flow rate. The new Cambiare range has 130 part numbers in the range with 50% sourced from OEM manufacturers.

The air mass sensor insert range has 10 part numbers available that cover over 70 OE references. This is because although there are many various designs of air flow housing available there are relatively few designs of sensor available. The insert is used when replacing the housing is not required. The insert is held in place by 2 screws and is a simple and cost effective alternative to fitting a direct fit air mass sensor.
EGR Valves (Exhaust Gas Recirculation) are used to re-circulate a portion of exhaust gas back into the combustion process. The aim of this is to reduce the amount of oxygen entering the chamber, in order to reduce the temperature reached during the combustion process. This reduction in combustion temperature limits the production of Nitrogen Oxide (NOx), one of the most harmful emission gases. As the re-circulation of exhaust gas does not harm the engine in any way it is an efficient way of reducing emissions. EGR valves are found in all modern diesel engines and some small petrol engines and are either pneumatically or electronically operated.. The Cambiare range offers both Pneumatic and Electrical EGR Valves all of which are 100 % OE.
