Where is dual cycle used?

Dual combustion cycle finds application in Diesel engine. Dual combustion cycle is an ideal air standard closed cycle, which has five processess where heat addition be firstly at constant volume and next at constant pressure and rejection at constant volume. This has application to use in Diesel engines.

What is dual cycle process?

Dual cycle, or limited pressure cycle, is a thermodynamic cycle that combines the Otto cycle and the Diesel cycle. A more capable approach would be to model the combustion process in both Otto and Diesel engines as a combination of two heat-transfer processes, one isochoric process, and one isobaric process.

Which fuel is used in dual cycle engine?

diesel fuel
Compression-ignition dual-fuel engines use diesel fuel for pilot ignition of the natural gas.

Which fuel is used in dual combustion cycle?

diesel
A dual fuel engine is an engine designed to burn predominantly natural gas but with a small percentage of diesel as a pilot fuel to start ignition. The engines operate on a cross between the diesel and the Otto cycles.

Why is the dual cycle known as a mixed cycle?

In this cycle, part of heat addition occurs at constant volume while the rest is at constant pressure. The dual cycle is also called mixed or limited pressure cycle. This thermal efficiency can be converted in terms of measurable quantities as it was done for Otto and Diesel cycle.

What are the assumptions in dual cycle?

The working fluid is assumed to be a perfect gas. There is no change in the mass of the working medium. All the process that constitutes the cycle is reversible. Heat is assumed to be supplied from a constant high-temperature source and not from chemical reaction during the cycle.

What fuel is used in dual cycle engine?

What is the other name of dual cycle?

mixed cycle
What is the other name of dual cycle? Explanation: Dual cycle is combination of otto cycle and diesel cycle. Dual cycle is also known as mixed cycle.

Who discovered dual cycle?

The dual combustion cycle (also known as the mixed cycle, Trinkler cycle, Seiliger cycle or Sabathe cycle) is a thermal cycle that is a combination of the Otto cycle and the Diesel cycle, first introduced by Russian-German engineer Gustav Trinkler, who never claimed to have developed the cycle though.

What is dual cycle?

Dual cycle is also called as mixed cycle or limited pressure cycle as it is a combination of Otto cycle and diesel cycle. Most of the cars of present time are working on dual cycle instead of diesel cycle.

How do you calculate the efficiency of the dual cycle?

Thermodynamically, the efficiency of the Dual cycle is given by Work done by the system = Heat supplied (Q S)- Heat rejected (Q R) W = Q S – Q R From the processes 1 → 2

What is the difference between Otto cycle and Diesel cycle?

The Otto cycle is a constant volume cycle and the Diesel cycle is a constant pressure cycle. In a practical scenario, in the constant volume cycle, the combustion might not take place at the constant volume because of the chemical reaction during the combustion need some time to take place.

What is the difference between air standard cycle and dual cycle?

So this is the difference between the air standard cycles and the practical engines. This Dual cycle is a compromise between the Otto cycle and the Diesel Cycle. so it is called the mixed cycle or Limited pressure Cycle. The P-V and T-S diagram for the Dual cycle is shown below.
