Greeting

We sincerely appreciate your continued patronage and guidance.

Our company specializes in test systems and solutions for engine‑based test benches.
Since our founding in 1948, for nearly 80 years, we have supported our customers’ manufacturing as an indispensable partner behind the scenes.

To address key challenges faced by our customers—such as shorter development cycles, diversified fuels, reduced emissions, and improved product reliability—we operate two core businesses:
the Test Bench Engineering business and the Powertrain Engineering (contract testing) business. Through these pillars, we deliver a wide range of products and services globally.

We also actively promote human‑capital‑focused management and are committed to developing talent that creates new value.

We will continue to stand alongside our customers’ future—more deeply and more sincerely— so that we remain a partner who enhances the value of their manufacturing. We humbly ask for your continued support and patronage.
