This paper presents experimental test results of a new compressed natural gas direct injection (CNG-DI) engine that has been developed from modification of a multi cylinder gasoline port injection (PI) engine. The major modifications done are (1) the injection system has been modified to gas direct injection using new high pressure gas injectors, (2) compression ratio has been changed from 10 t...

Go-karts are popular sport mini-car in western countries, and there are gaining prominence in developing countries such as Nigeria. Its performance is determined by the chassis design and the braking system is its lifeline. Because of the lack of a suspension system and differentials, a good chassis must be able to bend and twist. This Go-kart is powered by a Yamaha Vino Automatic Petrol 2-str...

Active automotive engine vibration isolation is considered where both stationary and transient engine-induced excitations as well as plant non-linearity are considered. The adopted control strategy targets the dominating spectral components of the excitation and achieves narrow band vibration isolation using feedback of disturbance states estimates. Time-varying gain-scheduled observer design, ...

The nanoparticles formed in motor vehicle exhaust have received increasing attention due to their potential adverse health effects. It has been recently proposed that combustion-generated ions may play a critical role in the formation of these volatile nanoparticles. In this paper, we design an experiment to measure the total ion concentration in motor vehicle engine exhaust, and report some pr...

In this paper, adaptive filtering is adopted for active automotive engine vibration isolation where both transient and stationary engine internal excitations as well as structure flexibility are considered. The adaptive filtering problem is formulated using a linear regression model representation. This allows for an application of a general family of state-of-the-art recursive parameter estima...

One of the important features of the racing car is the power to weight ratio, and to this end, weight has been considerably reduced by the use of carbon fibre in the modern Formula One car. The weight saving obtained from carbon fibre components is utilised by the strategic placement of ballast (since there is a minimum weight limit set by the racing authority, the FIA), ordinarily as low as po...

In Formula Society of Automotive Engineers (FSAE) cars engine heat management serves as an important factor for the performance vehicle. Therefore, a proper design sidepod is crucial optimal cooling since sidepods are designed to direct airflow through radiator. Also, play role in aerodynamic vehicle, factors such drag and lift must also be considered along with engine. This paper brings forth ...

The fueleconomy.gov web site, run by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency, lists different estimates of fuel economy for passenger cars and trucks. For each vehicle, various characteristics are recorded such as the engine displacement or number of cylinders. Along with these values, laboratory measurements ...

It is thought that active noise control (ANC) is able to control not only loudness but also auditory impression; however, few studies have focused on changes in the auditory impressions of noises through ANC. Some previous studies have reported significant correlations between subjective preference/annoyance of sounds and synchrony of the alpha activity, e. In this study, auditory impressions ...

Due to the release of several electric vehicles (EV) to the car market, the number of sales is expected to increase soon. Concerning in-vehicle information systems (IVIS) of EVs, different kinds of information need to be communicated to the driver. E.g. displayed numbers for current energy consumption or the energy left in the batteries are hereby critical in terms of a potential increase of ra...
