A look into the future
Diesel range from Denso
Published: 04 March, 2015
Replacement parts such as spark plugs and alternators may come to mind when you think of Denso but the firm is keen to emphasise its extensive range of diesel parts also available to the aftermarket. Denso has been making injection pumps since 1957 and was the first company to introduce 2,000 bar diesel common rail technology in 1995 and a 2,500 bar system came along in 2013. It supplies fuel injection pumps and diesel injectors, with a total of 100 part numbers for CR pumps and injectors covering at least 329 applications. Diesel fuel filters and suction control valves are also available. Looking ahead, Denso is working on a 3,000 bar common rail system. Other innovations include a similar size but more efficient fuel pump and redesigned components and new materials to further improve performance and reduce the diesel's impact on the environment.
- Cutting dead space
The number of engine management components available from Denso is set to increase with a range of cam and crank sensors, as well as further additions to its MAF sensor and fuel pump ranges for popular models.
- Give diesels a helping hand
Soot is a common problem for diesel engines and older vehicles may struggle to pass the emissions test during an MOT because of it so Liqui Moly suggests using its Pro-Line Diesel System Cleaner in this instance. The concentrated treatment has been developed to remove chemical deposits from the fuel system, injection nozzles and combustion chamber. The can is poured into the fuel tank and gets to work after a few miles, dissolving deposits while the fuel is burnt and according to Liqui Moly, this results in the engine regaining its original power, fuel efficiency and exhaust gas values. It also protects against corrosion and minimises the effects of w
- Pressure sensors
A blocked DPF is often down to failed active or passive regenerations due to driving conditions and can also be down to other component failure such as the EGR system. Pressure sensors detect a filter that is beginning to get clogged up when it is about 45% blocked and the vehicle will then attempt an active regeneration to burn off the soot. It needs to be driven at a constant throttle for several minutes to achieve this, if a vehicle only ever doers short, town commutes then this process is never completed. If it gets to 75% blocked the DPF warning light will come on and the vehicle may go into 'limp home' mode - it may be possible to do a forced regeneration using a diagnostic tool such as Blue Print's G-Scan. If the light is ignored, the filter will completely block and will need to be replaced. Blue Print's range of DPFs include 31 part numbers for 44 applications.
- Boost MPG
Increased power, acceleration and fuel economy is the name of the game with Randstad's Diesel Power Tuning product. The tuning box module, developed by a race engineer in Holland, is programmed to tweak a specific vehicle model and is fitted to an under bonnet sensor. The unit does not alter a vehicle's ECU or remap the engine and will not affect a vehicle's warranty. It can be easily removed if the vehicle is sold and transferred to another.
- Grinding gears
Chicago Pneumatic has unveiled its first composite angle grinder for the vehicle service market. The new CP75XX series boasts a powerful 1.1HP (840W) governed motor, providing a high material removal rate enabling users to reduce the time taken to complete their tasks. The new series is available in 4-inch, 4.5-inch and 5-inch grinding wheels, cutting wheels, flap wheels; providing users with added versatility to best suit their application.
