All About The Alloys – Valve Seat Selection For High Performance Applications
We can’t make any sweeping generalizations about what kind of seats work best in a performance engine application because “performance” covers a lot of territory, everything from hot street engines with stainless steel valves to top fuel drag racing and NASCAR engines with titanium valves. Seat requirements vary depending on the application, what kind of
Connecting Rod Reconditioning: More to it than you might think
The connecting rod plays a vital role in the engine. But a connecting rod is under tremendous stress, with the weight of the piston sitting on top, changing direction thousands of times per minute. This continuous stopping and changing of direction combined with the weight of the piston and speed of the engine hammer on

Crankshafts:Stock and Performance
The crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The leverage effect of the force exerted on the crank journals twists the shaft and converts the up-and-down reciprocating motion of the pistons into rotational motion of

Engine Bearings: Stock & Performance
The importance of the engine’s bearings can’t be over-emphasized. The bearings support the crankshaft and connecting rods, and in pushrod engines also the camshaft. The bearings provide a surface for the friction-reducing oil film that allows the parts to spin without rubbing metal against metal. It’s a tough job because of the high loads created
The Mid-range Diesel Engine Market
The diesel engine market is a very complex one, but it can be broken down into three basic categories: light-, medium- and heavy-duty. These categories could then be broken down further into on-highway, off-highway and agricultural. In 2004 roughly 1.5 million new diesel engines were produced in North America, a whopping 79.6 percent of which

Surfacing Equipment Options
On older cast iron engines with conventional soft-faced head gaskets, as long as the surface finish on the cylinder head and block deck is roughly 60 to 100 microinches Ra (roughness average), the head gasket should cold seal and remain leak-free for the life of the engine. But on late model bimetal (aluminum head/cast iron
Coretalk: GM, DaimlerChrysler Join Forces To Produce Hybrid Automobile Engines By ’07
Although financial terms of the agreement weren’t disclosed, the collaboration is likely to involve an investment of hundreds of millions of dollars between the automakers. The first of the vehicles is to debut in 2007 – when Toyota has said it hopes its hybrid model sales will total several hundred thousand worldwide. GM, which has

Washington Way: Battle Over Heavy Duty OBD Repair Info Continues
In early 2003, the California Air Resources Board (CARB) decided to extend to heavy-duty vehicles the on-board-diagnostics information access rules then applicable only to automobiles and light duty vehicles. These access rules specify the information which the vehicle manufacturers have to make accessible from within the OBD system on their vehicles and from outside the
Piston Ring Technology: Stock and Performance
Piston rings have one of the toughest jobs inside an engine. They’re slammed up and down between the ring lands thousands of times a minute; they’re subjected to searing temperatures and extreme pressures; and they’re constantly scraping back and forth against the cylinder walls. In spite of all of this, the rings are expected to

New Clean Diesel Technology
With gasoline prices in the U.S. bouncing around the two dollars per gallon mark, record high oil prices and growing uncertainty over the price and availability of future oil supplies, any new technology that can give consumers more bang for their buck should be welcomed. Domestic vehicle manufacturers have virtually abandoned further development of electric
