“…Obecnie koncern VW-Audi stosuje w niektórych konstrukcjach silników o zapłonie iskrowym układy zasilania z dwoma kompletami wtryskiwaczy. W jednym silniku oprócz wtryskiwaczy wtryskujących benzynę bezpośrednio do cylindrów, są także wtryskiwacze wtryskujące paliwo do kolektora dolotowego [14]. Podobne rozwiązanie stosuje również firma Toyota [15].…”

Piston combustion engines used for propelling vehicles have a significantly harmful impact upon people’s living environment. As a result, for many years now the development of combustion engines has been to a large extent defined by growing legal ecological requirements. New constructional solutions are being introduced, the conditions of working processes in engine cylinders are being changed, new solutions are being implemented in fuel feeding systems, air intake systems and fumes exhaust. The composition of conventional fuel is being modified, alternative fuels are being sought for and new types of powering systems are being developed. This paper presents the comparison of selected efficiency and ecological indicators of two engines having the same construction, but different in the type of powering and the method of controlling the process of supplying fuel and air into cylinders. One of the engines is Perkins 1104D-44TA, mechanically controlled and equipped with a feeding system with distributor injection pump. The second one is the Perkins 1104D-E44TA, electronically controlled, where fuel is supplied into the cylinders by means of the Common Rail system. During the tests, the engines operated according to two load characteristics. Hourly and specific fuel consumption as well as concentration levels of main components of exhaust fumes and smokiness have been iden-tified and compared.

“…For light-duty gasoline vehicles, in response to the upcoming implementation of the China VI emission regulations, advanced exhaust gas aftertreatment technologies (e.g., GPF) must be applied to reduce the vehicle tailpipe emissions in addition to the adaptation of engine internal parameters, such as air/fuel ratio, fuel injection strategy, and combustion phasing, to further optimize the combustion system in order to reduce the engine-out raw emissions [6][7][8][9]. The technology of DPF to solve the problem of diesel particulate emissions has been applied for many years, and its effectiveness on the reduction of particulate emission has been well confirmed [10,11].…”

An Experimental Investigation of the Impact of Washcoat Composition on Gasoline Particulate Filter (GPF) Performance

et al. 2020

The forthcoming implementation of the China VI emission regulations, which are currently the most stringent around the world targeted at light-duty gasoline engine vehicles, will not only further restrict the emissions of gaseous pollutants, but also put forward, for the first time, the requirements of particulate number (PN) emissions with a limit set at 6 × 1011#/km. To achieve the stringent emission targets, the ceramic wall-flow gasoline particulate filter (GPF) will be effective to achieve the reduction of the particulate number tailpipe emissions in a way similar to the widely applied diesel particulate filter (DPF) in diesel engines. This paper investigated the effect of a coated gasoline particulate filter (GPF) on the PN emission and engine performance. The effects of two factors, including the washcoat powder material bulk density and type of coating, were studied with regard to three primary performances of GPF, including high three-way catalytic performance, low pressure drop, and high PN filtration efficiency, according to the original equipment manufacturer (OEM) requirements. The outcomes show that the use of high bulk density materials resulted in a low washcoat volume and hence a decrease of flow resistance and backpressure, in addition to high PN filtration efficiency. The type of coating had notable influence on the backpressure and PN filtration efficiency. The coating length and coating amount both had notable influence on the backpressure and PN filtration efficiency.
