BACKGROUND An elevated risk of lung cancer in truck drivers has been attributed to diesel exhaust exposure. Interpretation of these studies specifically implicating diesel exhaust as a carcinogen has been limited because of limited exposure measurements and lack of work records relating job title to exposure-related job duties. OBJECTIVES We established a large retrospective cohort of truckin...

This paper presents performance study of Peugeot MM540 diesel engine using biodiesel prepared from used cooking oil. Transesterification process is followed to produce bio diesel and is blended with diesel in different proportion of 22:78 and 24:76 by volume and named as blend B22 and B24 respectively. Engine was run at different loads (0, 15, 30, 35, and 40kg) with constant speed of 1000rpm se...

here are six main classes of gaseous contaminants which are routinely described in Tautomotive exhaust (a term which will be used here to refer to both automobile and diesel exhaust). As shown in Table 1, carbon monoxide (CO) is the largest component of automobile exhaust whereas the oxides of nitrogen (NO ) constitute the main components of diesel exhaust. x Even though nitrogen oxides contrib...

This study compared the pulmonary carcinogenicities and selected noncancer effects produced by chronic exposure of rats at high rates to diesel exhaust and carbon black. The comparison was intended to provide insight into the likely importance of the mutagenic organic compounds associated with the soot portion of diesel exhaust in inducing pulmonary carcinogenicity in diesel exhaust-exposed rat...

1. The possible carcinogenicity of diesel engine exhaust is a topic that the Industrial Injuries Advisory Council (IIAC) has had under review. In September 2015, it published an Information Note relating to lung cancer, bladder cancer and diesel exhaust emissions across a range of occupations.1 That Information Note set aside for separate consideration the case for prescribing under the Industr...

Particulate Matter (PM) is one of the major harmful substances in diesel exhaust gas. Technologies like the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) have been positioned at the exhaust to reduce the quantity of harmful substances released to the environment. This paper highlights the factors that affect combustion in diesel engines and the potential of the introductio...

During three separate studies involving characterization of diesel particulate matter carbon nanotubes (CNTs) were found among diesel exhaust particles sampled onto transmission electron microscopy (TEM) grids. During these studies, samples were collected from three different diesel engines at normal operating conditions with or without an iron catalyst (introduced as ferrocene) in the fuel. Th...

A comprehensive study on the methanol as an alternative fuel has been carried out. A four stroke four cylinder diesel engine was adopted to study engine power, torque, break specific fuel consumption, break thermal efficiency and exhaust temperature with the fuel of fraction methanol in diesel. In this study, the diesel engine was tested using methanol blended with diesel at certain mixing rati...

Over the past 115 years the invention of a compression ignition engine by Rudolph Diesel in the 1890s has contributed significantly to the productivity of many nations, owing to the widespread use of larger diesel powered equipment in most industrial activities. The down-side in terms of occupational health has been the exposure of a large number of workers to the complex mixture of toxic, gase...
