Air Filter and Selected Vehicle Characteristics

Abstract

While a vehicle is driving, the air filter is gradually being clogged. Thus, there is a condition for air mass delivered into the engine’s cylinders to be reduced. It can further degrade the vehicle’s ability to accelerate and, therefore, have an impact on road driving safety, or it can eventually make a vehicle performance worse or cause a change in the exhaust gas composition. The article pays attention to the impact of clogged air filter on selected vehicle characteristics including a vehicle’s dynamic features, fuel consumption and composition of the exhaust gases. The measurements have been performed under laboratory conditions. For higher result objectivity, the measurements have been done under some extreme conditions as well, with both the air filter fully clogged and forced air induction. The importance of the article lies in quantification of the impact of clogged air filter on selected vehicle features. The results from this article show a relatively low impact of air filter on the features studied. The biggest differences were measured under extreme conditions when the air filter had been almost fully clogged, or the air had been delivered into the engine under pressure.

Empirical study of the effect of the air filter on the performance and exhaust emissions of a diesel engine

“…The results indicate a relatively small effect of air filter pressure drop on the studied parameters of turbocharged engines, where a decrease in engine power in the range of 2-3% was registered. In contrast, the power loss of a naturally aspirated engine with ZI was twice as large -6.2% [63]. The paper [64] presents, in the speed range of n = 1000-2100 rpm, the results of a study of the effect of three technical states of the air filter (different pressure drop of the filter element) on the performance parameters (power, hourly and specific fuel consumption, boost pressure and exhaust gas temperature) of a modern Diesel truck internal combustion engine.…”

“…There are only a few papers in the literature addressing the effect of air filter pressure drop on engine performance and exhaust emissions [62][63][64][65]. Thomas et al [62] studied the effect of air filter pressure drop on changes in engine emissions of three modern trucks.…”

“…The effect of panel pressure drop (filter paper) of the air filter after the vehicle run on selected engine and vehicle parameters: power and specific fuel consumption, exhaust emissions and vehicle dynamics, is presented in [63]. Measurements were carried out on a chassis dynamometer using two vehicles, where the power unit was a turbocharged compression-ignition engine with air cooling, and in two vehicles with a SI engine, one naturally aspirated and the other turbocharged and air-cooled.…”

The Influence of Quality Management System on the Operation of Periodical Technical Inspection Stations

“…The final PTI product is therefore an evaluation of the technical condition of the vehicles [59]. However, the provision of this service is not a normal business but the safeguarding of the state's interest [60].…”

Application of FTIR-ATR Spectrometry in Conjunction with Multivariate Regression Methods for Viscosity Prediction of Worn-Out Motor Oils

“…In addition to the actual chemical aging of the oil, it is also degraded by residues of imperfectly burned fuel, condensed water or coolant penetrating through leaks, metal abrasive particles from the engine [7]. Furthermore, small dust impurities and contaminants from gritting materials on the maintenance of roads in the winter months, which are sucked in from the environment when driving with a clogged air filter, have an effect on the deterioration of the oil [8,9]. Motor oils in diesel engines are heavily contaminated with soot.…”
