になつている。 This has a structure in which a solenoid for increasing the amount of starting fuel gas is activated at the same time as the cell starter is activated, and the amount of fuel is increased while starting and rotating the engine.
〈発明が解決しようとする問題点〉
この構造では、吸気管が普通の長さのエンジン
の場合、混合気が充分高濃度に形成されて、確実
に始動できるが、吸気管が非常に長くなるエンジ
ンの場合に、吸気管の吸気抵抗が大きくなつて、
燃焼室の吸気量が少なくなり、吸気の流速が低下

が少なくなり、混合濃度が薄くなるうえ、吸入さ
れる燃料ガスの絶対量も少なくなるため、エンジ
ンの始動性能が悪化し、始動不良をひき起す。<Problems to be Solved by the Invention> With this structure, in the case of an engine with a normal length of intake pipe, the air-fuel mixture is formed at a sufficiently high concentration and can be started reliably, but the intake pipe becomes very long. In the case of an engine, the intake resistance of the intake pipe increases,
As the intake air volume in the combustion chamber decreases and the flow velocity of the intake air decreases, the amount of fuel gas sucked out of the air in the mixer decreases, the mixture concentration becomes thinner, and the absolute amount of fuel gas sucked in decreases. As a result, the starting performance of the engine deteriorates, causing starting problems.
しかも、始動性が悪いことから、セルスタータ
は作動時間が長びいて耐久性が低下するうえ、バ
ツテリの電力消費も大きい。 Moreover, since starting performance is poor, cell starters have a longer operating time and reduced durability, and also consume a large amount of battery power.
なお、吸気管が非常に長くなるエンジンの一例
として、ヒートポンプ駆動用で、コンプレツサと
一緒にケーシングに内装されるエンジンがあり、
ケーシング外に臨むエアクリーナがケーシング内
の奥に位置する吸気ポートから遠く離れてしまう
ため、吸気管が非常に長くなる。 An example of an engine with a very long intake pipe is an engine that is used to drive a heat pump and is housed inside the casing together with the compressor.
Since the air cleaner facing outside the casing is far away from the intake port located deep inside the casing, the intake pipe becomes extremely long.
