Does each cylinder have a spark plug?
Each cylinder has a spark plug and a piston. The highly compressed air-fuel mixture is ignited by the spark.
Why do some engines have 2 spark plugs per cylinder?
By having two spark plugs per cylinder, your aircraft engine is more reliable, produces more power, and burns fuel more evenly. And when you combine all three, you get an ultra-reliable engine that keeps you aloft until you decide it’s time to land.
Why are Hemi engines so powerful?
The Hemi engine, by design, does a better job of burning all the fuel in the cylinder. Also, because of its design versus a flat head, the surface area is smaller and that means less heat escapes, plus peak pressure can be higher. Also advantageous, is the size of the valves.
Why is the LS so popular?
High performance, versatile design, aftermarket parts, and affordability are just some of the factors that fortify the long-lasting popularity of the engine. Due to widespread LS enthusiasm, Holley sponsors an LS fest where hundreds of LS-swapped vehicles are shown off by their owners.
Why are LS Motors so popular?
The LS engine family is known for having smaller proportions than its competitor’s engines, making it much easier to swap into cars with small engine bays. You can achieve better performance and economy with an overhead cam but at the cost of a much larger and heavier engine.
What’s better LS or LT?
LT vs LS engine: So which is better? If we’re talking about raw power per liter, then the newer LT1 offers more. At the same rpm range, the newer V8 can offer around 30 more horsepower. If what you’re after is more power without relying too much on forced induction, then this will matter a lot.
Is LT better than LS engine?
The LT blocks are more robust in design than the LS, thanks to its gusseted water jackets. This is one reason why the LT aluminum block can take up to 900 horsepower, and the L8T iron block should be safe in the 1,200 horsepower range.
What’s the difference between LS and LSX?
The LSX (note the capitalized “X”) is a race variant of the lightweight LS7 engine. This 7.0L (427ci) version of the Gen IV small block went into the 2006 Corvette. In contrast to the ‘vette motor, the LSX has a cast-iron block that handles a lot more horsepower. Here the “x” indicates an engine is of the LS family.
