Introduction
This document outlines the type of Diesel Particulate Filter (DPF) regeneration system used in the 2.8L Prado (1GD engine), focusing on whether it utilizes engine injectors or a separate injector for DPF regeneration.
Problem
The concern is understanding how the 2.8L Prado’s DPF system functions to determine if it uses engine injectors for post-combustion fuel injection, which can lead to oil dilution.
Solution
The 2.8L Prado (1GD engine) uses a separate injector specifically for DPF regeneration. This injector is located in the exhaust system, distinct from the engine’s primary fuel injectors.
