Triton kicks in with MIVEC

Mitsubishi finally shoehorns its advanced, aluminium MIVEC turbodiesel engine into the Triton.



We’d always rue that our northern neighbours were privy to more advanced engines and tech in their vehicles. Case in point, the Thais got their hands on the Mitsubishi Triton with the more efficient MIVEC aluminium alloy block engine due to the availability of Euro 5 diesel there; the root cause of engine’s unavailability here.
 
However, Mitsubish Motors Malaysia (MMM) has now refreshed the Triton sold in Malaysia and leading the list of improvements is the new 2.4-litre MIVEC turbodiesel with VGT and aluminium alloy block featuring the marque’s iconic Mitsubishi Innovative Valve timing Electronic control system (MIVEC) technology that is a first for the pick-up segment here.


 
MMM has tweaked the 2.4-litre turbodiesel MIVEC engine to cope with the sulphur-licious Euro 2M diesel here. Power figures for the new mill come in at 179bhp at 3500rpm with 430Nm at 2500rpm of torque, (identical to the Thai version that runs on Euro 5 diesel) even with our Euro 2M although the caveat is that the exhaust emissions quality will drop. Fuel consumption has been improved by 15 per cent as well.
 
“About 15 years ago, the Mitsubishi L200 was the first pick-up truck in Malaysia to be offered with an automatic transmission. In 2008, the Mitsubishi Triton raised the bar by being the first to offer a 3.2-litre engine, and in 2012 the Triton VGT became the first truck in Malaysia to use Variable Geometry Turbo,” said Yang Won-Chul, Chief Executive Officer of MMM.


 
Diesel engines promise vastly improved fuel efficiency chiefly with the use of high combustion pressure that result in side effects such as high NOx emissions. A number of manufacturers have been working on reducing the compression ratio of diesel engines to increase the emission quality. Mazda has achieved it with their SkyActiv-D tech and Mitsubishi has gone down the same route with similar results.
 
The 2.4-litre MIVEC turbodiesel engine has a compression ratio of 15:1, spitting distance of petrol engines and the SkyActiv-D mills as well. However, reducing the compression ratio has its side effects as well with cold start performance the cardinal sinner.


 
Mitsubishi has alleviated the issue with its MIVEC tech that allows accurate control of the intake valves. Prior to this, the MIVEC system was only available in petrol engines.
 
Furthermore, the lower compression ratio opens the door for lighter materials in the block’s construction, aluminium in this case. The end result is an engine that is 30kg lighter.


 
With the introduction of the MIVEC turbodiesel powerplant, the number of variants stands at six but only the top four get the new engine. The bottom two variants make do with the previous iron-block 2.5-litre turbodiesel mill.
