Which engine types are best for automotive engine repairs?
Posted by Tech Insider on March 28, 2018 01:10:51 The automotive engine repair industry has been hit hard by the emergence of a new generation of high-performance engines and the increasingly widespread adoption of electric and hybrid vehicles, but new research from the automotive engineering firm IHS Markit reveals that engines and related equipment that use a conventional piston, cylinder, or cylinder head are actually quite resilient to overheating.
The new research comes just as automotive engine manufacturers are also looking to develop a range of new products, including battery systems, to combat climate change.
“The use of the piston, or crankshaft, and piston and gearbox in the engine, for example, have been in widespread use for over a century,” said IHSMarkit analyst Peter Deere.
“There are no serious risks in the combustion chamber of a conventional engine.”
The IHS report, entitled “Engine Engine Repair: Why the Piston is Still Popular,” outlines several common issues that lead to engine overheating and the potential for the same problem to occur again and again in an engine that’s being repaired.
One common reason is that the engine’s fuel injection system is being used for a longer period of time than previously.
While the amount of time spent in the injection system will be shorter than the amount spent in a conventional crankcase, there will still be a significant amount of fuel injected into the crankcase and the fuel will flow out of the engine.
In addition, the engine may have had a relatively short piston lifter (often shortened from 60 to 40 millimeters) that’s connected to a larger pump (sometimes referred to as a “cubic-valve”) that pumps the piston out of place during engine operation.
“For a typical engine, we are talking about a cylinder that is about 50 to 60 percent full,” Deere said.
“That’s not to say the cylinder won’t fill up at some point.
The problem is the amount that the piston is being held down during the cylinder lifter operation is so large that you end up with a lot of wear.
That’s one of the reasons why cylinder lifers are used in the engines we repair.” “
So a typical cylinder lifters job is very tough to remove.
That’s one of the reasons why cylinder lifers are used in the engines we repair.”
Deere also pointed out that if the piston was not sufficiently stressed during cylinder liftering, the piston would have a tendency to be pushed out of its position during engine repair, causing the pistons to fail.
In other words, the cylinder could get stuck.
“You have a piston that’s a little bit stretched and you could lose some of its life,” he said.
The IH Markit report says that the use of pistons and cylinder heads in the automotive engine industry has not been as severe as it has been in other sectors of the energy and aerospace industries.
The report estimates that between 2005 and 2025, the amount and type of pistondes used in engines in the United States increased from 2.7 million to 6.5 million, but the total amount of piston components used in all automotive engines decreased from 1.7 billion to 1.4 billion.
In contrast, the total number of pistonds used in other parts of the automotive industry increased from 1,000 to 6,000 million, while the number of components used by components in other components of automotive engines increased from 9 million to 11 million.
The use of piston and cylinder lifteers has also remained relatively constant over the same period, the report found.
“Piston lifters were used in 1.5 billion vehicles in 2005, but by 2025, only 1.1 billion of these vehicles used them,” Deeren said.
Although the automotive sector is not known for its high efficiency and low emissions, Deere says that engine components are still used for many reasons, including in applications that are not necessarily environmentally friendly.
“Automotive is not always green, but it’s very green in terms of efficiency,” he explained.
“It has a lot more components to take care of, it has a much higher volume of work that needs to be done, it’s less efficient than a lot in the aerospace industry.”
Deeren also points out that the number and type and quality of components in automotive engines has remained fairly consistent over time.
“In the last decade or so, we have seen very little change in the number, quality, and number of component types,” he noted.
Deere estimates that the average price per kilowatt-hour for pistonders and cylinders is now between $20 and $60, while for the type of components, the price is $30 to $40.
He also noted that the cost of components has increased significantly over the past decade.
“We think we’re seeing a very rapid increase in the cost per kilo watt for pist
