Yanmar Power Technology Co., Ltd., a group company of Yanmar Holdings Co., Ltd., will exhibit at the "8th International Construction and Surveying Exhibition (CSPI 2026)" to be held at Makuhari Messe from Wednesday, June 17 to Saturday, June 20, 2026.

Under the theme "ENERGY DIVERSITY, YOUR SOLUTION PARTNER," this exhibition will propose a wide range of solutions for a sustainable future, including a concept model of an industrial hydrogen engine and the "Compact ATD (After Treatment Device)," which will be exhibited for the first time.

Main Exhibition Contents

Compact ATD (New Product)

This device purifies and reduces harmful substances (such as PM and NOx) emitted from the internal combustion of diesel engines using filters and catalysts. By adding the compact Compact ATD to our lineup in addition to the Separable ATD (conventional ATD), we can now meet a wider variety of customer needs than ever before.

Clean Gas Engine: TNG Series (4TN88B/LPG & Gasoline Bi-fuel)

The "4TN88B" was developed for industrial machinery and achieves low fuel consumption, high reliability, and a compact design. Compared to conventional gas engines, the "4TN88B" has a more compact overall engine design, achieving more efficient combustion while maintaining compatibility with diesel engines. It also features stable long-term operation while suppressing CO2 emissions.
