Ever since developing our first four-stroke engine in 1933, we have continuously worked to develop new models that meet the customer's needs, constantly making firm improvements that have resulted in Akasaka's current line of original, high-quality engines.
The "TYPE AX " engines with the aim of producing a smaller and lighter engine with lower fuel consumption when compared to “TYPE A .”
| Ocean vessel | Cargo vessels, tankers |
|---|---|
| Engine output（kW） | Min1,176 / Max 1,912 |
| Engine speed (min-1) | Min 260 / Max 320 |
The "TYPE A" engines have been developed with the concept of using a longer stroke to achieve higher output with reduced fuel consumption.
| Ocean vessel | Cargo vessels, tankers |
|---|---|
| Engine output（kW） | Min1,618 / Max 3,309 |
| Engine speed (min-1) | Min 210 / Max 310 |
The "TYPE K "and "TYPE E" engines were developed as a compact, energy-saving model that incorporates a combination reverse-reduction gear.
| Ocean vessel | Fishing boats,high school training boats |
|---|---|
| Engine output（kW） | TYPE K：Min956 / Max 1,471 TYPE E：Min1,323 / Max 1,618 |
| Engine speed (min-1) | TYPE K：Min 370 / Max 420 TYPE E：Min 420 / Max 470 |

In the years since Akasaka became a licensee of Mitsubishi Heavy Industries in 1960, the Akasaka - J-ENG UEC engine has become one of the large-scale two-stroke engine manufactured in Japan. This engine is used in powering cargo vessels, tankers, refrigerated cargo vessels, car carriers, and other ships.
| Ocean vessel | Cargo vessels, tankers |
|---|---|
| Engine output（kW） | Min2,130 / Max 7,560 |
| Engine speed (min-1) | Min 89 / Max 230 |
The "TYPE LSE "are environmentally-friendly engines that meet the market's demands for reliability. The state-of-the-art TYPE LSE engines were jointly developed by Mitsubishi Heavy Industries and Wartsila.
| Ocean vessel | Cargo vessels, tankers |
|---|---|
| Engine output（kW） | Min2,350 / Max 11,040 |
| Engine speed (min-1) | Min 93 / Max 167 |
The "Type LS2" high-performance engines incorporate the latest technology along with the knowhow developed with the LA and LS type long-stroke engines, for improved labor savings and reduced energy consumption. Comprehensive CAE strength studies have enabled us to achieve a lighter, more compact engine.
| Ocean vessel | Cargo vessels, tankers |
|---|---|
| Engine output（kW） | Min1,655 / Max 11,560 |
| Engine speed (min-1) | Min 95 / Max 215 |
