Diesel Engine Borescopes

Due to diameter limit of diesel engine injector holes, there are not many low price videoscopes / borescopes can be used for diesel engines, especially articulating borescopes. Now we have several 180 degree articulating borescopes with small diameter ( 4mm / 0.157" and 4.5mm / 0.177") probe cameras, which are suitable for diesel engine inspection without dissemble it. 

The affordable versions are USB articulating borescopes (Model D3245 and D3145) and WiFi/USB borescope (Model: W2240 and W2145). They can be connected to a PC, laptop, mac, Chromebook, or Android tablet or phone.

CX-4010i and CX-4010M are a fully articulating borescope with joystick control. The diameter of probe camera is 4mm/0.16" and length is 1 meter. The camera can be bended back completely to 180 degree, and can be turned around 360 degree. 

Above are some pictures taken with Vividia D3145, D3245 and W2145 inside a diesel Duramax engine.

These smaller diameter videoscopes are great tools for heavy-duty techs (HD techs).
