Burned MMT comes into contact with the oxygen sensors that stick up into the exhaust stream after the exhaust comes out of the engine and goes through the catalyst.

(Return tabled) Question No. 130 Mr. Francis Scarpaleggia: With regard to rail safety in Canada: (a) for the period of 2006-2012, which railways were permitted to operate with a single operator; (b) for the period of 2006-2012, which railways had permission to leave trains unattended for limited periods of time on main lines with or without an idling locomotive(s); (c) for the period of 2006-2012, which railways had permission to leave trains unattended for limited periods of time on side lines with or without an idling locomotive(s); (d) with regard to the railways in (b) and (c), under what specific conditions could the trains be left unattended; (e) what legislative or regulatory framework governs local emergency preparedness plans i ...[+++]n the event of a rail accident; (f) with respect to the plans in (e), (i) who is responsible for creating and executing such plans, (ii) by whom are they audited, (iii) how often are they audited, (iv) against what criteria are they audited; (g) by whom and how often are municipalities through which freight trains pass provided with regular reports on (i) the state of local emergency preparedness in the event of a rail accident, (ii) the state and maintenance record of the railway lines within their borders, (iii) the materials, hazardous or not, that are transported through their jurisdiction; (h) if reports referred to in (g) are not provided, why not; (i) how many of the DOT-111 railway tank cars and the DOD-112 tank cars are in use in Canada, for each year since 2006; (j) for each year since 2006, how many rolling stock and track safety inspectors were employed at Transport Canada, broken down by (i) province of work, (ii) oversight responsibility; (k) for each year since 2006, how many rolling stock and track safety inspectors employed by Transport Canada were responsible for inspections in (i) the Greater Montreal Area, (ii) the municipality of Pointe-Claire (iii) the municipality of Beaconsfield, (iv) the municipality ...

The environmental benefits of natural gas in transportation are clear, up to 30% fewer CO emissions and up to 90% less smog-causing particulate matter. Continued government support and commitment to implementing the natural gas road map, which includes a commitment to research and development, will help hasten the transport sector's option of increased natural gas use.

‘defeat device’ means any element of design which senses temperature, vehicle speed, engine speed and/or load, transmission gear, manifold vacuum or any other parameter for the purpose of activating, modulating, delaying or deactivating the operation of any part of the emission control and exhaust after-treatment system and which reduces the effectiveness of the emission control system under conditions which may reasonably be expected to be encountered in normal vehicle operation and use.

All filter types shall have a 0,3 µm DOP (di-octylphthalate) collection efficiency of at least 99% at a gas face velocity between 35 and 100 cm/s.

A gas face velocity through the filter of 35 to 100 cm/s shall be achieved.
