When reforming is not used, the fuel and exhaust pass through CV2 unchanged. The basic concept of TCR involves using exhaust heat to promote on-board reforming of hydrocarbon fuels into syngas (a mixture of carbon monoxide and hydrogen). The upper inner control volume (CV1) contains the combustion chamber and piston. Click to enlarge.
The Truck and Bus rule requires truck owners to install diesel exhaust filters on their rigs, with nearly all vehicles upgraded by 2014. Owners must also replace engines older than the 2010 model year according to a staggered implementation schedule that extends from 2012 to 2022. Earlier post.) Earlier post.).

It expands all the way to ambient pressure before the exhaust stroke. The power is produced in almost a 50-50 split between the combustion (central) and exhaust (largest) pistons. Transfer from the combustion cylinder to the exhaust cylinder takes place when the exhaust cylinder volume is minimal. and O’Malley, E.
