The accurate air-fuel ratio (AFR) control is crucial for the exhaust emission reduction based on the three-way catalytic converter in the spark ignition (SI) engine. The difficulties in transient cylinder air mass flow measurement, the existing fuel mass wall-wetting phenomenon, and the unfixed AFR path dynamic variations make the design of the AFR controller a challenging task. In this paper, an adaptive AFR regulation controller is designed using the feedforward and feedback control scheme based on the dynamical modelling of the AFR path. The generalized predictive control method is proposed to solve the problems of inherent nonlinearities, time delays, parameter variations, and uncertainties in the AFR closed loop. The simulation analysis is investigated for the effectiveness of noise suppression, online prediction, and self-correction on the SI engine system. Moreover, the experimental verification shows an acceptable performance of the designed controller and the potential usage of the generalized predictive control in AFR regulation application.

Looking forward to Lithuania becoming a member of the EU it is very important to use a larger amount of renewing fuel. Based on economic and environmental considerations in Lithuania, we are interested in studying the effects of ethanol contents in the blended ethanol‐petrol fuel on the engine performance and pollutant emission of SI engine. Therefore, we used engine test facilities to investigate the effects on the engine performance and pollutant emission of 3,5 % and 7,0 % ethanol in the fuel blend and special additives, which reduce emissions and increase octane rating. The tests were carried out in the laboratory on a chassis dynamometer with two different cars. The experiment results showed that ethanol used in a fuel blend with petrol had a positive influence on engine performance and exhaust emission.

The One

Methanol (CH3OH) is the one of an alternative fuel for SI engine. Methanol has a similiar charakteristic and fisik properties to gasoline. This study using methanol-gasoline fuel blend (M10, M20 and M40). The aim of this study was to determine the effect of using methanol-gasoline fuel blend of  fuel consumption, exhaust emission, power and torque. In the experiment,  an engine three-cylidre 12 valve with tecnology DOHC Mivec and ECI MPI injection System 1193 cc was used. With a little modification that is using methanol controler to maximize the result of research. The experimental result showed that the fuel consumption decrease with the use of methanol-gasoline ful blend. Each of these reductions in fuel consumption for the M10, M20 and M40 are 1 %, 3% dan 3%. The Power and Torque is increas while using fuel blend than gasoline and it also decrease exhaust emission
