Abstract
The present invention relates to an intake system for natural gas engine. An intake system for an engine is provided. A conduit is configured to direct a combustible mixture to a cylinder head. A mixing unit is coupled to the conduit. The mixing unit includes a fuel doser configured to dispense fuel into the conduit and a first mixer positioned downstream of the fuel doser. The first mixer is configured to mix air and the fuel. The mixing unit further includes a exhaust gas doser configured to dispense exhaust gas into the conduit and a second mixer positioned downstream of the exhaust gas doser. The second mixer is configured to mix the exhaust gas with the air and the fuel to make the combustible mixture. An air intake throttle is configured to direct the air into the mixing unit.
