When discussing engines, it is important to know that they are the heart of your vehicle. The Detroit Diesel Series 60 Non EGR has been used in large motor vehicles such as 18-wheelers and transport buses for many years. As time has progressed, the engines became more reliable and more affordable to fix with the help of after-market parts. Below are some of the most prevalent differences between the old and new style Series 60 engines.
DDEC I to DDEC IV
To improve the performance and response of diesel engines, they have been governed by various electronic control modules (ECM) throughout the years, starting with the Detroit Diesel Electronic Control or DDEC I and ending with the DDEC IV. The first system, DDEC I, lasted from 1987 to 1992, when it was replaced by DDEC II. All Old Style Series 60 11L & 12.7L engines were controlled by DDEC I, II or III until 1998. In 1999 the New Style Series 60 engine was introduced with a new ECM, DDEC IV. This new, more advanced ECM is one of the major differences between the Old Style and New Style Series 60 12.7L engines. The new ECM allowed for greater control through the use of more engine sensors. The other major change was a new, more durable two piece piston design with a steel crown and aluminum skirt capable of handling more horsepower. By 2001, the Series 60 14L New Style engine was introduced and offered large vehicles a 14L displacement option. The power was increased by up to 575hp and 1850 pounds of torque. This is all because of a large stoke crankshaft being installed.
Reliability and Longevity
The main difference that truck operators will notice between the older, mechanical diesels and the electronic engines of today is their fuel efficiency, reliability and longevity. Even though many believe that things were built better in the past, the newer style engines like the Series 60 have upgraded components designed and built to last an extended period of time. Since trucks now spend many hours on the road, manufacturers are held to higher standards for their engines. Many users find that the Detroit Diesel Series 60 engine is the most reliable engine of all. Lightweight, fuel efficient and great for hauling anything.
When installing a newer electronic engine it is essential that you have a computer and the appropriate software that will help you optimize it, whereas in the past a computer interface was not needed. These programs help to run diagnostic checks of every part of your engine to make sure that it is working efficiently and to its best standard. If not, it will show you what part of the engine needs to be taken care of.
The John Deere Power-Tech PSX 6135HFC95 is an inline six-cylinder 13.5L (824ci) diesel engine capable of generating 617 horsepower at 1,900 rpm and a torque of 1,962 ft-lbs at 1,600 rpm. With a 5.20×6.50” bore and stroke, single overhead camshaft, valve train with four valves per cylinder, a compression ratio of 15:3:1, a sequential fixed and variable-geometry turbochargers induction system, electronic unit injection at 33,000 psi and air to air inter cooler, this engine is in the forefront of diesel technology. The engine requires an oil change every five hundred hours. The head material is cast gray iron alloy while the block material is cast gray iron. The crankshaft material as well as the camshaft is forged steel. The engine is just over five feet in length and a tad more than three feet in width. It is five feet high and weighs 3,699 pounds or 1,678 kilograms. The engine has a cooled exhaust gas re circulation system, diesel particulate filter and oxidation catalyst as its emission system. It complies with the emission norms of EPA Interim Tier 4, CARB and EU Stage III B.
What stands out in the engine is the low-pressure fixed turbo and a high-pressure variable-geometry turbo working in sequence, the one-piece cast design using a heavy-duty, gray iron alloy material, the high-carbon steel camshaft with induction-hardened lobes to reduce noise and to increase life and the full-floating steel pistons with crankshaft of high carbon forged steel that can resist extreme heat and offer precise alignment. The attention to detail makes this engine a wonder.
Modern emission standards have been getting stricter by the day. Power or high performance is thus an expensive or an elusive attribute. The Power-Tech PSX 6135 smartly uses a cooled exhaust gas re circulation, a powerful injection system, a substantially large diesel particular filter and a diesel oxidation catalyst to adhere to the emission standards. The 13.5L Power-Tech PSX 6135HFC95 is a victory of industrial design and engine architecture. It is needless to say that the engine has already found numerous takers in the world of fire pumps and oilfield drills.
