119005-77051 Intake Air Heater for Komatsu Equipment CK20-1 CK25-1 SK1020-5 | Construction Machinery Spare Parts
The 119005-77051 Intake Air Heater is a core cold-start component for Yanmar 4TNV94 engines in Komatsu skid steers CK20-1, CK25-1, and loader SK1020-5. It preheats intake air to ensure reliable cold starts, smooth idle, and reduced emissions in low-temperature conditions, critical for consistent operation of construction machinery.
Function: This component is powered by the vehicle's battery and designed to heat the incoming air charge, which facilitates faster starts, reduces white smoke (cold emissions), and minimizes engine wear during ignition in chilly conditions.
