<p>A fuel vaporization unit (10) for delivering fuel vapor and air to an induction passage of an internal combustion engine, the unit (10) including a vacuum chamber (11) having air inlets (12, 13, 14) for transport air, the transport air being a proportion of the total air required for combustion, a fuel inlet (17) through which fuel can be delivered to the chamber (11), a fuel vapor outlet (15) through which fuel vapor and transport air can be delivered downstream to the induction passage, a heater means (32) for delivering heat to the chamber (11) to promote vaporization of fuel within the chamber (11) such that under the influence of negative pressure downstream of the chamber (11) transport air is drawn through the chamber (11) along with fuel vapor in order to deliver a mixture of air and fuel vapor through the fuel vapor outlet (15) downstream to the induction passage.</p> |
