Abstract
An internal combustion engine includes at least one combustion chamber, a main body, at least one purification device, and a cooler. The main body includes therein the at least one combustion chamber, and an exhaust flow path configured to allow exhaust gas flowing out of the at least one combustion chamber to flow down. The at least one purification device is arranged in the exhaust flow path of the main body. The cooler is configured to cool the at least one purification device. Each of the at least one purification device includes a purification member and a case. The purification member is configured to purify the exhaust gas. The case contains the purification member.

A wheeled land vehicle comprising an internal combustion engine, the internal combustion engine comprising:
- at least one combustion chamber;
- a main body including therein the at least one combustion chamber and an exhaust flow path configured to allow passage of exhaust gas flowing out of the at least one combustion chamber;
- at least one purification device arranged in the exhaust flow path of the main body;
- and
- a cooler located inside the main body and configured to cool the at least one purification device,
- wherein:
- each purification device of the at least one purification device includes:
- a purification member configured to purify the exhaust gas;
- and
- a case containing the purification member,
- the exhaust flow path has at least one exhaust outlet that is configured to allow the exhaust gas to flow out of the main body, and
- for each purification device of the at least one purification device, the purification device is arranged in the exhaust flow path with a portion of the case protruding from a corresponding exhaust outlet of the at least one exhaust outlet to outside of the main body and of the internal combustion engine.
A wheeled land vehicle comprising an internal combustion engine, the internal combustion engine comprising:
- at least one combustion chamber;
- a main body including therein the at least one combustion chamber and an exhaust flow path configured to allow passage of exhaust gas flowing out of the at least one combustion chamber;
- at least one purification device arranged in the exhaust flow path of the main body;
- and
- a cooler located inside the main body and configured to cool the at least one purification device,
