a class of kirchhoff type systems with nonlinear boundary conditions considered in this paper. by using the method of nehari manifold, it is proved that the system possesses two nontrivial nonnegative solutions if the parameters are small enough.

Abstract This study presents the optimization of intake manifold and optimized flow rate acetylene gas which acts as a low reactivity fuel to achieve superior performance emission characteristics used in Reactivity controlled compression ignition (RCCI) engine. Intake is one engine components are an important factor determining quality combustion. A very recent evolution RCCI using temperature ...

The intake manifold and its components play a key role in the proper formation of air–fuel mixtures suitable for correct engine operation. In this article, starting from original design fitted to an optically accessible spark-ignited engine, new solution was developed so as allow application high-speed imaging fuel jet located between runner valves (Port Fuel Injection). To compare two designs ...
