The N47 engine debuted in March 2007 the facelifted BMW 1 Series E87 and E81 was also available E82 E88, which were introduced same year. replaced M47 that had been production for 8 years. construction underwent several modifications, so injection system changed, cylinder head now consists of two parts, block is made aluminium. Two main versions are known: N47D16 (1.6 L) N47D20 (2.0 L). In case...

Combustion in the cylinder of a spark ignition engine, particularly under low load conditions, is subject to cycleby-cycle variations due to factors such as mixture quality and quantity and internal exhaust gas recirculation. The major result of this phenomenon is an increase in the variability of indicated engine torque at a given engine operating point. Automotive control problems dealing wit...

This paper analyzes the vibration behavior of an in-line 4-cylinder, 4-strokes, internal combustion turbocharged direct injection gasoline engine. A detailed multi-body numerical model of the engine prototype was used to characterize the whole engine dynamic behavior, in terms of forces and velocities. The crank train multi-body model was created starting from engine geometrical data, and the a...

 Abstract: This study deals with modeling of heat flux at the external surface of combustion chamber wall in an internal combustion (IC) engine as a function of crank angle. This investigation results in an inverse heat conduction problem in the cylinder wall. Alifanov regularization method is used for solving this inverse problem. This problem study as an optimization problem in which a square...

A Micro Gas Turbine (MGT) can be considered as an alternative to the internal combustion engine as a range extender for electric vehicles. The MGT produces less raw exhaust gaseous emissions such as HC and CO in aerospace and static applications compared to the internal combustion engine. In addition, the MGT weight is less than an equivalent internal combustion engine and potentially can reduc...

Abstract – Dynamic modeling and identification of an internal combustion engine (ICE) model is presented in this paper. Initially, an analytical model of an internal combustion engine simulated within SIMULINK environment is excited by pseudorandom binary sequence (PRBS) input. This random signals input is chosen to excite the dynamic behavior of the system over a large range of frequencies. Th...

In conventional internal combustion engines, the periodic fuel combustion in cylinders and oscillating masses result in pulsating engine torque. In hybrid powertrains, the electrical motor can be used to control such pulsations. The main originality of this paper is to present an efficient harmonic controller synchronized with the engine speed: the feedback law controls the Fourier parameters o...

Changing the compression ratio and presence of turbocharger are two important issues, affecting on performance, and exhaust emissions in internal combustion engines. To study the functional properties and exhaust emissions in regards to compression ratio at different speeds, the numerical solution of the governing equations on the fluid flow inside the combustion chamber and the numerical solut...

Control of the inner engine torque of a combustion engine is very crucial for the overall performance of a dynamical combustion engine test bench. The main problem thereby is the usually unknown system behavior of the combustion engine, the time delay of the accelerator actuator which is used to control the combustion engine. In general the combustion engine is mounted on a combustion engine te...
