Diesel Particulate Filter (DPF) filters and Exhaust Gas Recirculation (EGR) valves are installed in most modern cars, and are meant to restrict emissions and improve efficiency. However, these can fail or become clogged. At AC Tuning, we can remove these from your vehicle and improve its performance.

The STD/DX engine is Dual Point Fuel Injection (DPFI) which has two (2) fuel injectors, a Main Injector and an Auxiliary Injector. ... The Multi Point Fuel Injection (MPFI) engine has four (4) fuel injectors, one at each cylinder.

The most significant area for diesel car owners is stricter rules on the permissible level of emissions of cars fitted with a DPF. If a car's exhaust emits visible smoke of any colour, it will fail the MOT test. ... It's already illegal to drive a vehicle that has had its DPF removed.

Abstract: Exhaust gas recirculation (EGR) is an effective strategy to control NOx emissions from diesel engines. The EGR reduces NOx through lowering the oxygen concentration in the combustion chamber, as well as through heat absorption.

AdBlue is only applicable to diesel engines and is an emissions reduction technology that complements existing DPF technology. Diesel cars fitted with a DPF may not necessarily feature an AdBlue tank. However, cars with an AdBlue tank always feature a DPF as part of the overall emission control solution.

EIGRP is based on DUAL (Diffusive Update Algorithm) while OSPF uses SPF (Shortest Path First) algorithm. The major difference between these two algorithms lies in how they calculate the shortest routing path.

A DPF typically uses a substrate made of a ceramic material that is formed into a honeycomb structure. In order to reduce emissions from diesel vehicles, diesel particulate filters capture and store exhaust soot, which must be periodically burned off to regenerate the filter.

DPF stands for Diesel Particulate Filter. It traps soot. There IS a catalytic converter in diesels; the box after the DPF is the SCR, Selective Catalytic Reduction. It combines the exhaust with the DEF in the presence of the catalyst to convert the NOx into nitrogen and water.

A blocked DPF can be incredibly expensive to replace. ... The reason is simple: DPFs, compulsory in every diesel vehicle made since 2009, and found in many more manufactured before that date, are now failing in huge numbers. 'Blocked DPF' is an increasingly popular search term on Google.

Euro 5. Applies to all new cars registered from 1 January 2011. Benefits: Heralded the introduction of diesel particulate filters (DPFs) for all diesel cars. A particulates limit was also introduced for direct-injection petrol engines.

It is illegal for drivers to use a car with the DPF removed, but it is not illegal for garages to take them out. 5 live Investigates followed the progress of a car which had its filter removed through MOT tests at three different garages.

Unlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter; however, the DPF does not retain small particles and maintenance-free DPFs break larger particles into smaller ones.

The Exhaust Gas Recirculation or EGR system is one of several vehicle emission control systems. It helps reduce the amount of the nitrogen oxides (NOx) in the exhaust gases. Nitrogen oxides are normally formed in the process of combustion in the engine cylinders.

The exhaust gas recirculation valve serves as the gateway that opens and closes to control the flow of exhaust gases returning into the combustion chamber. There are different EGR valve designs but all of them function the same.

If you're not going to run OE fluid, at least stick with one type. Generally speaking, NO, not all ATF is the same. ATF+4, Dexron/Mercon, weird Pentosin varieties, modern synthetics, all are very different and using the wrong one can destroy an auto trans very quickly.

A PCV valve helps keep a constant pressure within the engine block by releasing oil fumes when they get to a certain pressure and sending them into the fuel system to be reburned with the gas. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.

Functionally they're all the same. Make sure that you use a metal case if you have high pressure fuel injection. Of course, the smaller the filter, the more often it should be changed.
