WITH the new CAT truck range now officially launched, attention is focused on which engines will be under the bonnet of trucks built this year.
NC2, the joint venture between Navistar and Caterpillar, built the initial batch of CT610 and CT630 CAT trucks with CAT C13 and C15 CAT ACERT engines.
These engines do not meet the new ADR83/03 emission regulations that came into effect on January 1.
CAT trucks with the C13 and C15 engines built and plated before the end of last year can be sold this year, but any new trucks will need cleaner engines.
With Caterpillar pulling out of the on-highway engine business, this means the CAT trucks will not run proper CAT engines. Given the rest of the truck is heavily based on International trucks, the natural question is how much of the CAT truck is really CAT?
NC2 says the CAT engine will live on after the initial batch of 300-400 CAT trucks with the C13 and C15 has been sold.
It has told Big Wheels that Navistar has bought the tooling for the 15-litre C15 engine block and will use it for a new engine that will be used in the CT630 as well as Navistar products.
Wearing the CAT badge, this engine will use the head and other components from the Navistar Maxxforce engine, which is based on technology sourced from German brand MAN as part of another joint venture.
NC2 product development boss Thomas D. Baughman says the engine is a great combination of technologies.
‘‘ We’ve taken the most complex parts of the engine and captured them from Caterpillar. We have taken the pieces that are state-ofthe-art and very timely such as turbocharging, the fuel injection and electronic controls and from the MAN side of the house.’’
The 13-litre engine for the CT610 will have no CAT DNA and will simply be a Maxxforce engine, which is essentially a MAN D26 tweaked for the US market.
Both engines are expected run exhaust gas recirculation EGR, for some time, although NC2 says it will use selective catalytic reduction ( SCR) systems in some markets other than the US and Australia, despite being strongly opposed to the technology.
Engine upgrade: the new CAT truck.
