What is the cut off ratio of a diesel engine?
The thermodynamic cycle which powers a diesel engine has four steps: 1. Adiabatic compression (compression with no heat transfer into or out of the reaction cylinder). 2. Heating at constant pressure. In a diesel engine, the heat generated by the compression step is so great that fuel spontaneously combusts as it's injected into the cylinder; however, this combustion is not instantaneous, so the gases inside the cylinder heat up and expand at constant pressure as the fuel burns. 3. Adiabatic expansion (this is the part where the cylinder is doing work on whatever the engine is hooked up to). 4. Cooling at constant pressure (the exhaust is expelled from the cylinder). The compression ratio is the ratio between the initial volume and the volume at the end of Step 1. The cutoff ratio is the ratio of the volume at the end of Step 1 (BEFORE the fuel is injected and burned) to the volume at the end of Step 2 (AFTER the fuel is injected and burned). The expansion ratio is the ratio of the volume at the end of Step 2 to to volume at the end of Step 3. In case this clarifies, (compression ratio) = (cutoff ratio) * (expansion ratio).

How would you find the surface area of a cylinder with a cylinder bored out of it?
if the cylinder is on the inside, it would not affect the surface area. otherwise, subtract the part of the inside cylinder that touches the outside from the cylinder

How sides does a cylinder have?
A cylinder has two sides - an inside and an outside
Where is the expansion valve on a 2003 PT Cruiser?
The expansion valve is located inside the accumulator/dryer. It does not have a separate expansion valve like other cars. The PT Cruiser is classified by Chrysler as a Truck (probably because it gets such poor gas mileage - 18mpg city for a 4 cylinder), not a car. Trucks usually have an accumulator or a liquid line. If you believe the problem to be an expansion valve, replace the dryer.

Where is expansion valve on 1997 caravan?
Inside the hvac housing inside vehicle.requires removing dash and hvac housing to get at evaporator,and then replacing expansion valve!have fun.
Does micrometer measure inside of a cylinder?
Yes. An inside micrometer or bore micrometer can be used for measuring the bore of a machined cylinder.
What do you mean by cyinder in engine?
The cylinder, is the body of the engine that has been bored out in order to place a piston inside of it. The piston rides inside the cylinder.
