a basic guide to big rig diesel motors
manufacturers: who's who
Manufacturers of diesel motors today are constantly struggling to maintain the stringent emission standards imposed by government regulations and at the same time, produce a reliable product.
Recent changes within the industry have triggered the purchase of diesel
motor manufacturers, by big rig manufacturers.
With the exception of Cummins, all other engine makers are owned or partly-owned by truck manufacturers.
keep their costs sharpened, the truck manufacturers limit the choice of motors available in their products, so the motors available in
big trucks is much more limited than in past years.... definitely not a
good thing for the buyer.
It's been a positive move for the manufacturers, as they are now not dependent on outside sources for their production.
For example, if you were to order a Peterbilt
with a Detroit engine, the build time would often be delayed, due to
the wait time for the production and delivery of the engine. Not so now.
Diesel Engines - Who's Who
- Detroit -- Detroit Diesel is partnered with Freightliner/Western Star.
- Volvo Diesel -- Volvo makes their own engines and they’re also available in.
- International Diesel -- The only diesel company not using DEF technology, International makes their own motors for their own trucks.
- Paccar Engines-- Paccar now manufacturers motors for their own trucks (Peterbilts and Kenworths). Petes and Kenworths can also be ordered with a Cummins engine. Paccar trucks are the only big trucks with a choice of engine.
- Caterpillar Engines -- Caterpillar no longer manufactures a heavy truck engine, although Cat parts are still available. They chose to bow out of the market after struggling to produce a reliable motor that met the tough emission standards and regulations. What a shame that it's no longer an option to order a truck with a Caterpillar motor.
- Cummins Engines -- Cummins
is an independent engine manufacturer. These motors are only
available in Paccar products: Kenworth and Peterbilt trucks.
- Diesel Oil -- In keeping with the changes in today’s engines, diesel motor oil makers are offering synthetic engine oil as well as the traditional product.
- Motor Problems --Diesel engine troubleshooting
issues are best handled in a dealership’s shop because today's new motors
are completely computerized. However, there are some things that the trucker can watch for or do to help prevent unnecessary breakdowns and extra costs.
- Picking the Best -- Choosing
the best engine for the specific work the vehicle will be doing, is one
of the most important decisions you’ll be faced with when spec'ing or buying a truck.
- Do your homework and choose a motor that will not only give you decent diesel fuel economy, but will stand the test of time and keep you out of the repair shop.
- Biodiesel Fuel -- With diesel fuel prices being the biggest expense for truckers, the trucking
industry struggles for alternatives to traditional diesel. Although
not a completely practical or safe alternative yet, biodiesel is an
alternative that some folks are considering.
