Most folks don’t realize this but Paccar has been building diesel engines since 1956 and was one the first to put a turbo on a diesel engine in 1959. All of this experience and expertise came to play when Paccar designed and introduced the latest engine the MX-13.
The MX-13 offers many innovations that can help everyone from large fleets to an independent owner-operator save time, save money and stay on the road. We are going to take a look at a couple of specific things that in our experience makes the MX-13 a great engine.
Everyone knows that weight is the enemy, all that weight drives up fuel costs and increases braking distances and extra weight in the engine is less weight for your load! Even though the MX-13 is packed with weight saving features, two of them stuck out for us.
The first is the cam shaft. The Paccar MX-13 uses a single camshaft that is positioned low in the block to help reduce engine noise and to help keep the overall size of the MX-13 smaller. In addition, using a single high strength steel camshaft reduces weight considerably and the overall complexity of the engine.
The other really interesting innovation is the Compacted Graphite Iron that is used in the block and cylinder heads. Compacted Graphite Iron adds higher tensile strength and better resists the heat of the modern diesel engine. Compacted Graphite Iron is 75% stronger and stiffer than grey iron AND lighter! All this adds up to fuel savings and less weight, in short, the Paccar MX-13 offers an excellent power to weight ratio.
The other innovation that we have found folks love is the Integral Engine Brake, this unique cam actuated design produces excellent performance without the noise, complexity and added engine height and weight of other systems.
These are just a few of the features we have found to be excellent reasons to choose a Paccar MX-13 in your new trucks, at the end of the day it will save you time, money and keep you on the road!
