New Study Shows Feasibility of Liquid Propane Direct Injection Engines
Research study shows new technology can enable widespread production and commercialization of lower-carbon lifecycle medium-duty LPG engines.
CNG and Propane Engine Builds
Building engines for a living means building whatever a customer wants. With a growing market for alternative fuels you might find yourself building an engine for a customer who wants his engine to run on compressed natural gas (CNG), liquefied natural gas (LNG) or propane (liquefied petroleum gas or LP).
Propane Industry Unveils ‘Propane Clean American Energy’ Tagline
The Propane Education & Research Council (PERC) has announced the launch of a new logo and brand identity for propane, PROPANE Clean American Energy. The logo, anchored by the iconic image of an American bald eagle, highlights propane as an increasingly American-made alternative fuel at a time when U.S. propane production from natural gas liquids
Green Strategies: Propane – A Gas on the Rise
The issue of the automotive and heavy-duty industry moving toward more alternative fuel useage will always be an important topic of discussion for the rebuilding industry. And, no matter which side of the fence you are on regarding a reduction in petroleum in today’s vehicles, alternative fuels may provide more engine-related opportunities to your business.
A New Take on the Rotary Engine
What if we could design a new rotary engine that addresses certain limitations without violating the laws of physics? This is what LiquidPiston has been working at for over a decade.
Rottler Report with Jeff Gunther of Gunther’s Machine & Rebuilding
Jeff Gunther of Gunther’s Machine & Rebuilding recently got a new Rottler SG9MTS.
The Re-Emergence of Rotary Engines
Rotary engines should not be discarded as technology of the past. Rather, they should be improved and used on a wider scale to power more efficient and greener vehicles.
Shop Solutions April 2021
Disassembling an old stuck engine can be challenging. When valves are stuck in the valve guides, try welding a nut to the face of the valve.
Motorcycle Valve Seats
As it related to valve seats, it is important to know a bit about the different materials used and when and where it is appropriate to use them.
Compound Turbo 6.4L Cummins
Looking to get the shop’s name out in public and compete in the Ultimate Callout Challenge with a true engine building statement, The Diesel Shop pulled out all the stops on this compound turbo 6.4L Cummins build. Find out why it dominated at the 2019 UCC event.
Valve Seats & Guides
Performing valve jobs is one of the most crucial areas of the engine building business. According to our most recent Machine Shop Market Profile, cylinder heads for gas engines account for nearly 16 percent of an engine builder’s production time – and it’s easy to see why.
MAHLE Kicks Off ‘7 Reasons’ Promotion with ‘Get Things Firing’ Prize
MAHLE Aftermarket North America “7 Reasons” promotion has opened, offering participants the opportunity to win a grand prize ‘Get Things Firing!’ grill package. Reason 1 of the promotion, tied to MAHLE Aftermarket engine component products, is open from July 22, 2019 through August 4, 2019.
Katech Signs Commercial Agreement to Build LPG Engines for Begas Motor
Katech has announced it signed a commercial agreement with Begas Motor of Madrid, Spain to build 250 liquid propane gas (LPG) engines over the next two years.
Antique Tractor Pulling
Just as how car racing first began, when the first two tractors were sold, the new owners must have decided to have a contest to see which tractor could outpull the other.
High Performance Heavy-Duty Engine Look at Diesels Through a Different Lens
Across much of the highway system of the U.S., heavy trucks race almost non-stop to their next destination. Actually, because of DOT regulations and self-enacted restrictions from nearly every fleet operation, those trucks are more likely to be driven safely and efficiently. On several race tracks across the United States, though, diesel tractors with C12
Understanding How Valve Seats Are Made, How They Work and What Can Happen When They’re Wrong
When it comes to engine cooling, the radiator is kind of a showoff. It sits right up front, catching the best breeze, dominating the conversation. And when it erupts in a cloud of coolant and steam, everyone knows about it. However, the engine valves (particularly the exhaust valves) shouldn’t be overlooked for the role they
Understanding Today’s Valve Seats
When it comes to engine cooling, the radiator is kind of a showoff. It sits right up front, catching the best breeze, dominating the conversation.

Let’s Talk Engine Oils
SN oils don’t have sufficient ZDP to coat all the engine components which are subjected to sliding friction. And, if that isn’t bad enough, a new oil specification, ILSAC (International Lubricant Specification and Approval Committee) GF-6 is on the horizon.
Valves and Seats
When it comes to engine components working together, there are few areas that share the same level of relationship as the valves and valve seats. The factors that affect this duo’s ability to reside in harmony inside an internal combustion engine encompass everything from material compatibility to thermal conductivity.
Engine Oil Changes and Innovations
It’s always helpful at the end of each year to reflect on what’s been accomplished and where we think our industry is headed. I think we should do this for the three types of oils you Engine Builder readers typically encounter.
