Evaporative Emissions Testing
At a glance
Millbrook offers evaporative emissions (hydrocarbon permeation) testing of vehicles and sub systems for development and homologation, in addition to tailpipe emissions testing.
Millbrook uses its significant experience in evaporative emission testing to support customers through the complicated test process. Millbrook is able to butane load evaporative canisters which can be used for canister interaction engine calibration testing.
Millbrook is able to condition and stabilize canisters by performing repeat loads and purges procedures.

Fuel vapors are composed of hydrocarbons, which are regulated on gasoline vehicles in most countries. Millbrook’s evaporative emissions test facility is designed and calibrated to perform a baking of vehicles to condition them, the regulated hot soak tests and the regulated diurnal emissions tests. During these tests the amount of hydrocarbons emitted by the vehicle is measured.
Millbrook’s variable temperature Sealed Housing for Evaporative Determination (SHED) emission test facility (also known as the VTSHED) is used precisely to determine the levels of hydrocarbon permeation. It is temperature controlled (15°C to 50°C) and located in close proximity to the light duty vehicle emissions chassis dynamometers and covers a variety of global emissions legislations.
