Transport

Heavy-duty trucks and buses account for about one-third of NOx emissions and one-quarter of PM emissions from mobile sources. In some cities, the contribution is even greater. The fine particles in diesel exhaust (known as particulate matter) pose serious health risks.

Diesel exhaust also has environmental impacts. PM from diesel engines contribute to haze, which restricts visibility. In addition, diesel exhaust contributes to ozone formation, acid rain, and global climate change.

Running vehicles on natural gas has a positive effect on the risks as outlined above, examples include:

CO2 - up to 10% reduction compared to Diesel.
Particulate emissions - reduced by 99%.
Carbon Monoxide - reduced by 90%.
Benzene – reduced by 97- 99%.
Nitrous Oxide - reduced by 85%.
Lead and sulphur - 100% reduction.
Gas engines are also quieter than diesel engines.

PRINS has developed an innovative range of core components for delivering CNG or LPG to electronic multi-point gas injection systems for bus and heavy duty vehicle applications for OEM and aftermarket customers.
