Saya sedang mencari bantuan profesional untuk merancang sebuah mesin otomotif yang berfokus pada Mesin pembakaran internal dengan target utama Emisi rendah. Proyek ini bertujuan menghasilkan konsep yang siap dikembangkan lebih lanjut menjadi prototipe fisik, termasuk analisis performa dan strategi pengendalian emisi yang efektif. Lingkup kerja yang saya butuhkan meliputi: • Perancangan konseptual dan model CAD 3D dari mesin pembakaran internal. • Perhitungan teknis—termasuk simulasi termal, aliran udara, dan emisi—untuk memastikan target emisi tercapai tanpa mengorbankan keandalan. • Rekomendasi material, sistem injeksi bahan bakar, dan teknologi after-treatment (catalytic converter, EGR, atau opsi serupa) yang relevan. • Laporan ringkas tentang estimasi konsumsi bahan bakar, output tenaga, serta langkah-langkah optimalisasi lebih lanjut. Saya terbuka berdiskusi mengenai pendekatan desain, metode simulasi, maupun integrasi solusi pendinginan atau transmisi di tahap selanjutnya apabila diperlukan. Fokus awalnya adalah menghasilkan desain dasar yang solid dan mampu memenuhi regulasi emisi modern.

Untuk konsep mesin rendah emisi, saya akan mulai dari bahan bakar, kapasitas, daya/RPM, duty cycle dan standar emisi tujuan. Parameter ini menentukan geometri awal, kebutuhan pendinginan serta pilihan injeksi/EGR/after-treatment; model CAD saja belum membuktikan kepatuhan emisi. Saya mechanical engineer dengan pengalaman 12+ tahun, menggunakan SolidWorks dan ANSYS Fluent/Mechanical. Portofolio saya mencakup CFD ventilasi dan sistem pendingin industri: aliran, distribusi temperatur dan pressure drop. Pendekatan tersebut relevan untuk studi awal jalur udara dan pendinginan mesin Anda. Saya menawarkan USD 22/jam. Usulan tahap awal adalah 24 jam (USD 528), sekitar 2 minggu, setelah input dan cakupan disepakati: matriks kebutuhan, layout CAD konseptual, neraca energi/perkiraan performa awal, satu studi aliran atau termal yang dipilih bersama, serta laporan asumsi dan rekomendasi material/opsi pengendalian emisi. Hanya jam aktual yang disetujui ditagihkan. Simulasi pembakaran/emisi terperinci memerlukan model bahan bakar, kondisi operasi dan data validasi; tahap lanjut itu diestimasi terpisah setelah baseline tersedia. Saya tidak menjanjikan sertifikasi emisi atau pembuatan prototipe fisik. Apakah ada mesin referensi/CAD awal? Mohon kirim target daya, bahan bakar, kapasitas, batas ruang, negara/standar emisi dan data uji yang tersedia agar kita memilih studi pertama yang paling bermanfaat. Salam, Gokay

Hello, I am interested in working on your low-emission internal combustion engine design project. I can support the project from the initial conceptual design through engineering analysis and preparation for prototype development. My approach would include developing the engine concept and 3D CAD model, followed by thermal, airflow/CFD, and performance analysis using appropriate simulation tools. I can also evaluate key parameters such as combustion efficiency, fuel consumption, power output, cooling requirements, and potential emission sources. For emission reduction, I can assess suitable strategies such as EGR, optimized fuel injection, combustion parameter optimization, and appropriate exhaust after-treatment systems such as catalytic converters. Material selection will also be considered based on temperature, mechanical loads, durability, and manufacturability. The final deliverables can include the 3D CAD model, engineering calculations/simulation results, preliminary specifications, emission-control strategy, and a concise technical report with recommendations for further optimization and prototype development. I am comfortable discussing the project requirements, target engine specifications, fuel type, emission standards, and preferred CAD/CAE workflow before starting. I would be glad to discuss the project with you and define the technical scope and milestones. Best regards

The risk here is achieving low emissions in an internal combustion engine without sacrificing reliability. I handle this by integrating emissions control directly into the conceptual design phase, not as an add-on. I will build the conceptual design and 3D CAD models of the internal combustion engine using SolidWorks, focusing on the combustion chamber geometry and port design for optimal air-fuel mixing. For technical calculations, I will perform thermal and airflow simulations using ANSYS Fluent to predict combustion characteristics and then run separate simulations to model the generation and reduction of key emissions like NOx and PM. I pick ANSYS for its proven accuracy in fluid dynamics and combustion. Material recommendations will favour ceramics for high-temperature components and low-friction coatings for pistons and rings. For fuel injection, I will specify a direct injection system, and for after-treatment, I will detail an exhaust gas recirculation (EGR) system integrated with a three-way catalytic converter, as these are proven for reducing NOx and CO/HC in gasoline engines. The final output will be a concise report detailing fuel consumption estimates and power output. The failure this job is most likely to hit is exceeding emission targets due to unaddressed internal combustion inefficiencies. I prevent this by running iterative simulations on the combustion process itself before finalising the CAD, making adjustments to the air-fuel ratio and ignition timing models. Track record on here: 5.0 across 10 reviews, 100% on time and 100% on budget. This means I deliver accurate designs on schedule and within cost. My question is about the expected fuel type for this engine concept. A proposed short call on Freelancer to settle the scope would cover the engine displacement and the specific emission standards you are targeting.
