Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis. The combustion parameters such as heat release rate, cylinder peak pressure, and max...

This paper proposes a novel algorithm for decision-making on autonomous lane change manoeuvre in vehicles. The proposed approach defines a number of constraints, based on the vehicle’s dynamics and environmental conditions, which must be satisfied for a safe and comfortable lane change manoeuvre. Inclusion of the lateral position of other vehicles on the road and the tyre-road friction are the ...

The steering torque at the handwheel, necessary to steer a car at zero speed, is discussed. Measurements made on a tyre alone on a static rig and measurements made on a car in normal trim are complemented by a mathematical system model. The model uses parameter values deriving partly from the tyre rig results, partly from the car specification and partly from the car results. It provides simula...

This study investigated the properties and sustainability of cement-bonded composites containing industrial residues such as wood chips, tyre fibres biomass combustion residues, i.e. bottom ash (BA) fly (FA). The effect cement-to-raw material (wood/tyre fibre) ratio (C/RM) aggregate content (BA FA) on thermal mechanical were investigated. Scanning electron microscopy (SEM) life cycle analysis (...

The Anti-lock braking system (ABS) is an active safety device in road vehicles, which during hard braking maximizes the braking force between the tyre and the road irrespective of the road conditions. This is accomplished by regulating the wheel slip around its optimum value. Due to the high non-linearity of the tyre and road interaction, and uncertainties from vehicle dynamics, a standard PID ...

Loss of braking power and rubber skidding on a wet road is still an open physics problem, as neither the hydrodynamic effects nor the loss of surface adhesion that are sometimes blamed really manage to explain the 20-30% observed loss of low-speed tyre-road friction. Here we report a novel mechanism based on sealing of water-filled substrate pools by the rubber. The sealed-in water effectively ...

This paper presents the modelling and simulation of a stable angle-based instability threat indicator for articulated off-road vehicles. First, a stable angle is represented by the vertical forces of four wheels and steering angle of an off-road articulated steer vehicle. Then a vehicle prototype model is built based on a specific wheel loader type and a tyre/terrain model. Finally, the prototy...

Abstract The production of tyres is one the most energy consuming manufacturing activities in rubber sector. In cycle a tyre, curing operation has maximum loss. This mostly due to extensive use steam as source heat and pressure vulcanization process. To author’s knowledge, no scientific work available literature where efficiency tyre press estimated by means comprehensive model all main compone...

The car-tyre friction injury has differences from other injuries. The components of injury which are burn, crushing, shearing, and degloving occur. Many treatment options can be performed for coverage of wound which are Vacuum Assisted Closure system (V.A.C), skin grafting, free flaps, local flaps and cross leg flap.
