Why would the g's on the Chevy 350 be so much higher than everything else? Piston speeds are slower, rpms are slower, so there is more time for the piston to reach its speed of 66mph. Oh, and when you calculate the force exherted on the rod by the acceleration of the piston, don't forget that...
Nitriding cranks is standard practice and is done by virtually all auto manufacturers today. I've never heard of anybody nitriding a cylinder. Woudl it create problems during the break-in because it is harder than the piston rings? Many motorcylcles (especially 2 strokes) have nickel plated...
Why don't you just have your water pump circulate water to water to tranny fluid, power steering fluid, and refridgerant heat exchangers placed wherever you want them in the car. Set up a cooling water header and run everything in parallel. You may need thermostats on some coolers. You will...
My motorcycle has transparent fuel lines, I think they are some kind of neoprene. I don't have any here with me so I can't tell you for sure. They start off blue, but after a few years they turn brown on the inside and lose some of their transparency.
You're right, motorcycles don't actually have a flywheel, they use the alternator as a flywheel. Formula 1 uses a multiple disk clutch very similar to what is found on a motorcycle and probably uses the basket as a flywheel because there is a lot of weight there.
Could be, I ride dirtbikes and they are tall so it is very easy to upset the balance and initiate a turn. They wheels have a very pronounced gyroscopic effect, and you can use this to initiate a turn. In order to make a left-hand turn, you push the left handle bar (turn them to the right) and...
Everything in automotive design is a compromise. A lighter flywheel gives better throttle response because there is less mass to accelerate, and shifts are shorter because it takes less time for the engine to decelerate from high rpms. Heavier flywheels improve rideability by reducing the rate...
Ok, I figrued out why big twins get better traction than the 4 cylinder engines. The engines with 2 large cylinders require more of energy be stored in a flywheel than a similarly displaced 4 cylinder in order to compress that large volume of air. A large flywheel means the rotating assembly...
Cranking it until you get oil pressure is good enough. The best way to clean cylinder walls is using soap and water or engine oil. Solvents like laquer thinners, mineral spirits, etc... don't pick up all of the small particles left in the scratches from the honing process. I don't think that...
Did the car come originally with forged pistons? I don't think it did. Forged pistons generally require more piston-cylinder wall clearance than cast pistons because they have a higher coeficient of expansion.
Flat tappet cams need to be broken in carfully because the increased friction of the still rough surfaces creates a lot of shear force which can knock the lobes off of the cam in short order. Most manufactuers reccomend a 2000-2500 rpm break in because that is when the cam gets the best oiling...
He criticizes manufacturers for reccomending an easy break-in period. I think the manufacturers do so because a new engine creates a lot of heat due to friction because the surfaces haven't worn in yet. This is especially apparent on air-cooled motorcycle engines when you have to shut them...
I know of an application that uses a staged turbocharger/supercharger. The emergency generator on our ship is a 2-stroke Detroit Diesel 8v92. The supercharger is necessary to overcome the scavenging deficiencies of the 2-stroke for fast startups necessary for emergencies. The turbo charger is...
Well, you said any combustion engine so that doesn't limit us to internal combustion. A steam engine is a form of combustion engine and reciprocating steam engines can make torque at 0 rpm.
I'm sure you meant internal combustion, though, so those 100 RPM slow speed 2-stroke diesels would be...
The reason the bike says to use unleaded only is because California requires the manufacturer to require the use of unleaded. In all reality, low lead fuels like avgas are probably the best for your engine and valves. The only reason for not running lead that I have heard is because it is...
Almost forgot to mention waste spark engines, they are common in single cylinder applications and many of today's modern applications. They fire once every revolution per cylinder.
They use pulses, and are for the most part are standard. A 4-stroke v8 pulses 4 times per revolution, a 4-stroke 4 cylinder pusles 2 times per revolution, a 2-stroke 4 cylinder pulses 4 times per revolution. I think you can figure out what other engine configurations do. Coil on plug setups...
I haven't done much work on large diesels yet, I am about to start by installing pistons in a 900kw generator on Wednesday. Anyways, to test for a bent connecting rod, pull the head of the number 3 cylinder and pull the head of any other cylinder head you feel like pulling. Then, take a dial...
Mercury makes a 2 stroke gas engine that is good for some 350hp, but it is a realativly low displacement engine, not like the one described earlier. Formula 1 boats use 2 stroke engines, possibly v8's also.
There are plenty of large displacement 2-stroke diesels, but they are very limited on...
