Overview
| MLIT filing number | 1139530 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | December 8, 2016 |
| Manufacturer(s) | Hino |
| Component | Computer (engine) |
| Production period | May 15, 2007 — October 2011 |
| Vehicles affected | 7,457 units |
Defect
On heavy-duty trucks, the engine control program is incorrect. When manual regeneration of the DPR (exhaust gas purification device) is interrupted frequently, fuel from post-injection migrates into the EGR cooler, generating carbon deposits that adhere to the intake valves. Extended parking after this condition increases the viscosity of the carbon deposits. This causes the intake valves to bind. In the worst case, a valve may fracture, producing abnormal noise and damaging the engine.
Corrective action
On all vehicles, reprogram the engine control software. If abnormal noise from the intake valves is detected during the post-reprogramming inspection, replace the complete cylinder head assembly.

状況
大型トラックにおいて、エンジン制御プログラムが不適切なため、ＤＰＲ（排出ガス浄化装置）の手動再生を頻繁に中断した場合、ポスト噴射による燃料がＥＧＲクーラに廻り込み、カーボンデポジットが生成されて吸気バルブに付着し、そのままの状態で長時間駐車するとカーボンデポジットの粘度が増加することがある。そのため、吸気バルブが摺動不良となり、最悪の場合、バルブが折損し、異音が発生するとともにエンジンが破損するおそれがある。
改善措置
全車両、エンジン制御プログラムを書き換える。また、書き換え作業後の点検で吸気バルブから異音がしている場合は、シリンダヘッド一式を交換する。
